I don't know these, but two years ago, a tourist had a 3D camera he had scratchbuilt at one of my volunteer-of-the-State events, and he showed me stuff of myself he'd taken the previous year. The effect is really quite impressive.

His homemade jobby was like a head-sized box and reminiscent of the old cameras you see in cowboy movies.

"If you tell me you can't sew, or paint, or build, then you're right; you can't, and you've failed yourself before even trying. But remember, there was a time when you couldn't walk or talk or even add, too. You changed that. The first thing you have to believe in is yourself." -laughinggravy2
