Draw a trololologram

Question

Your challenge here is to draw a trololologram.

You can choose any language.

The answer with more upvotes and the one that exploits more holes wins.

Rules for valid answers:

• You can't use any network resource or external file (except the source-code)
• You can't post someone else's answer
• You can't have it stored in any image format or pre-rendered (including base64 data:// uri's and any form of ascii art).
• You can't store the image in any database.
• You can't simply print/echo 'trololologram' (case insensitive)
• Explain your answers and what holes you exploited.
• The code must render the trolologram on the screen (minimum size of 90x90) and must be with a black border and white background. The rendered version can't "be invisible" or "hidden behind the screen" or similar.
• The image must show in the screen. It can't output the code to a file or anything similar (/dev/null doesn't count and virtual screens/viewports also don't count).

The main goal is to twist the rules and bend them at your own will and stil render a trololologram on screen.

Have fun!

Answer 1

For this challenge, I am posting five programs in this answer, all in Java.

Program 1

You can't simply print/echo 'trololologram' (case insensitive)

public class JustPrintIt {
    public static void main(String[] args) {
        System.out.println("trololologram");
    }
}

Program 2

You can't [...] pre-rendered ([...] and any form of ascii art).

public class AsciiArt {
    public static void main(String[] args) {
        System.out.println(
            "    ########################       \n" +
            "  ##                        #      \n" +
            "  #                          #     \n" +
            " #                            ##   \n" +
            " #                              #  \n" +
            " #                              #  \n" +
            "  #                            #   \n" +
            "  #                          ##    \n" +
            "  #                     #####      \n" +
            "  #            #########           \n" +

And finally...

Explain your answers and what holes you exploited.

So here it is:

The answer with more upvotes and the one that exploits more holes wins.

There is hole in this: you did not said that it must be a valid answer to be accepted!

Answer 2

Java 8

Here it is:

You can't use any network resource or external file (except the source-code)

I am reading the source-code.

You can't post someone else's answer

What about someone else's question?

You can't have it stored in any image format or pre-rendered (including base64 data:// uri's and any form of ascii art).

It is indeed not an image format. It is not ascii-art either, since all the characters are the same. It is not pre-rendered either, its source is just english text.

If you insists, this is ascii-art:

/-------\
|       |
| O   O |
|       |
| ----- |
\-------/

This is not ascii-art:

XXXXXXXXX
XXXXXXXXX
XXXXXXXXX
XXXXXXXXX
XXXXXXXXX
XXXXXXXXX

You can't store the image in any database.

It does not, but it saves an SQL's INSERT statement into a file.

You can't simply print/echo 'trololologram' (case insensitive)

Yes, I do not do simply that.

Explain your answers and what holes you exploited.

I am already doing that.

The code must render the trolologram on the screen (minimum size of 90x90) and must be with a black border and white background. The rendered version can't "be invisible" or "hidden behind the screen" or similar.

Indeed it has a minimum size of 90x90.

The image must show in the screen. It can't output the code to a file or anything similar (/dev/null doesn't count and virtual screens/viewports also don't count).

Indeed, it does not outputs code to a file, it outputs something else!

Answer 3

HTML/JavaScript _{^{(with a vengeance)}}

Since the humorous trollesque approach did not meet with an unadulterated success, here is my hackish JavaScript attempt, complete with its state-of-the-art HTML wrapper:

<script>function _(_,l,I,j){_-=i%$/5;l-=i*(j||.4)/$;return _*_+l*l<I*I/4}l='<pre>';$=90;for(
i=0;i<4e3;i++)l+=i%$?' %'[!(_(6,9,2,.8)|_(13,12,3,1)|_(7,48,5,1.4)|_(10,33,2,1))&(_(5,7,8)|_(
15,7,6)|_(-20,9,74)&_(38,9,72)&_(9,20,40)&_(-8,-10,64))]:'\n';document.write(l)</script>

(linefeeds added for readability)

Should produce something like this:

Skeptical people can see a live example here.

EDIT: let's review the rules point per point

You can't use any network resource or external file (except the source-code)

No problem there. You can run a script from within an HTML page directly from your hard disk.

You can't post someone else's answer

Check.

You can't have it stored in any image format or pre-rendered (including base64 data:// uri's and any form of ascii art).

Check.

You can't store the image in any database.

Check, provided the function parameters are not considered part of a database.

You can't simply print/echo 'trololologram' (case insensitive)

I was tempted to use the characters in "trololologram" instead of "%" as a filler, but that would have had an intolerable impact on the size of the program.

The code must render the trolologram on the screen (minimum size of 90x90) and must be with a black border and white background.

Check (you did not specify the interior color).

The rendered version can't "be invisible" or "hidden behind the screen" or similar.

Check.

The image must show in the screen. It can't output the code to a file or anything similar (/dev/null doesn't count and virtual screens/viewports also don't count).

As long as your browser window is not obscured, it's clearly showing the image on the screen. It's your genuine display, no cryptic device or virtual screen or viewport.

Explain your answers and what holes you exploited.

An HTML page, once rendered, is (among other things) an image displayed on the screen.
You can capture it, store it to disk, photoshop it, email it to relatives and friends, print it on genuines bits of dead trees and light a fire with it for all I care, but it's a friggin image.

About the ressemblance with the original trololologram, I do not claim to be an artist. Consider this code as a proof of concept. If someone wants to spend the hour(s) needed to tweak and add more elements to get closer to the original, he/she is welcome to do so.

Output:

Holes exploited:

You can't have it stored in any image format or pre-rendered (including base64 data:// uri's and any form of ascii art).

The ASCII art is generated by the script on the fly. The script itself only has info on which and how many characters it must draw onscreen and when start a new line.

You can't store the image in any database. The image must show in the screen. It can't output the code to a file or anything similar (/dev/null doesn't count and virtual screens/viewports also don't count).

The script doesn't create nor contain any files. When generated, the ASCII art is loaded onto the computer's RAM and then shown via CMD commands (without using any batch files, only cmd /c ).

The code must render the trolologram on the screen (minimum size of 90x90) and must be with a black border and white background. The rendered version can't "be invisible" or "hidden behind the screen" or similar.

The image displayed onscreen is way bigger than 90x90 and it's black on a white background.

Well it's not me that does the rendering, it's the browser.
And there is no ASCII here, only unicode :p.

Even ○ would be a better answer. – Ismael Miguel Feb 23 at 0:12

Well here it is:
