I have made a working TV out of bricks. It reads VHS style bricks to play simple short animations. Now, I shall give credit where credit is due. Thanks to IcyGamma for the idea, Trueno for the colorset I used, and Badspot for making Blockland, which I used to make this TV.
I have some screenshots now.
A VHS tape. The bottom part stores pixel information and the top part stores the animation itself.
The tape player. You duplicate the tapes inside to read them. Green starts the video and red stops it.
A screenshot of the default animation. The animation is of a guy waving. You can see the tape in the player.
This build was made 100% by me. I am not going to post a save because I fear it may fall into the wrong hands.
