Re: Tetris on Calulators! Misleading video on a page which is filled with advertisements. People making profit off other people's curiosity/naivity. Stuff like this should be banned from YouTube.
Re: Tetris on Calulators! To be fair, the guy does have the video in a playlist called "Fake Videos". http://www.youtube.com/view_play_list?p=02D8C7D733398A26
Re: Tetris on Calulators! Fine, so remove the advertisements. It's the combination of money and senselessness that bothers me.
It's not Jetris I developed my first Tetris clone, which ultimately became the Carbon Engine that powered TOD, on a TI-83 graphing calculator. And before I clicked through, I imagined that the video might have been a demo of one of these. But sure enough, it turned out to be a fake. The seven-segment LCD panel on a cheap five-function calculator doesn't have enough pixels for even the depicted "Well width: 7" variant, let alone one with connected blocks. This one (Halo on a Casio scientific) is even less plausible. But this one (SpongeBob video on a Merangue) is the most impressive: the calculator moves, and the display stays synchronized.
Re: It's not Jetris The four black dots around the LCD would be enough for motion tracking. It's a feature that advanced video editing suites have today.
