Indeed, they may have been yelling at me, but that is also because it's hard to beat a man at his own game.
The display was just two lcd projectors. Vector Flier definitely is best when projected on a wall, it's just one of those games where a monitor just won't cut it. Unfortunately they were not home-made. Although I have tried to build projectors in the past, i ended up melting some lcds (I definitely want to try it again with ultra-bright leds).
I'm excited that it brought back Tektronix flashbacks. I am really interested in exploring what's the most bare bone way to portray a space. It seems like back in the day, people couldn't go hyper-real so they had to make judgement calls for what is the essential data that needs to be portrayed to create a space. I think that process forced really novel thinking. I hope that now we have so many endless possibilities with current technology, we still step back and try to get at the core of the problems we are solving.
