I didn't even know. I was starting collage and had no idea how to do what he wanted, atleast some aspects of it. Also tired of working on this project for so long.
He was trying to take advantage of your obvious natural gift for thinking in abstract dimensions. Very specifically he was asking you to model elements of quantum mechanics that are notoriously hard to simulate on anything less than a bank of supercomputers at present. I felt offended ON your behalf. I forget what the x-prize for such a thing is, but it's a hefty chunk of probably 50K-250k.
If you're between projects have any interest in working on a slightly more complex game? More complicated playstyle wise, not concept wise. Pretty obvious you're working a few notches above my antique brain on the conceptual level. I've got a hum=dinger of an idea but i'm absolute shit as a coder. I'd be willing to split the take with you 50/50 as long as it remained just you & I working on it. If someone else came on board by mutual agreement it'd have to be split three ways, OFC. But it's basically a straightforward mechanic that I suspect will do quite well. I'd love to talk to you about it, presuming you'd agree to a Do Not Disclose/Non-disclosure agreement so i don't get screwed myself. I've given up way too many good ideas for other people to run off & profit off them over the years.
