Old School K9 TV Set

Another case of "couldn't find anything suitable on the Internet, so I made one instead".

This is a mock-up of an iconic color TV from the 1970s, and has 'on' and 'off' iRay materials for the screen. You can, however, use any 4:3 texture you like - for best results, use it also as an Emission surface. The picture tube has separate meshes & materials for the main picture and scanlines, so that you can keep or remove the scanline effect as desired.
