Advent Video Beam Television
The Advent VideoBeam is a big-screen television that was invented in the 1970s by Advent Corporation, founded by Henry Kloss. Both picture and sound are projected from the television's projector base towards a curved screen, where they are reflected back towards the viewer. It is a plug-and-play system, which means it has few adjustments, to make it easier to install.[1] In 1978, its advertised sale price was $3,000. [2]

gollark: RTL-SDRs are also very cheap (£30, or less for slightly lower end models).
gollark: As far as I know there are already ones around for most of the easy to receive ones.
gollark: It's entry 2.93e36 on my "should probably do but don't" list.
gollark: Because the second one is apparently pretty practical with a cheap SDR and some antennas, I believe some people on here do it.
gollark: Do you mean actually meddle with them or just receive them?
