Not to hijack the thread too much, but with the sort of thing you're doing, I'd seriously consider reaching out to people from the demoscene. There's a pretty large demo culture in Finland, and they'd be perfectly suited to the task, particularly the computational geometry and WebGL side of things. I'd be interested myself if I were in Helsinki.

I was implementing a proof of concept in WebGL for my product and thought, I wonder if someone has implemented a WebGL modeler yet? After a bit of search ran across Tinkercad... Was a super impressive product, and don't know why more people aren't aware of it.
