I got two 40x and one 42x projection t.v. lenses any ideas for a good craft out of them? Answered

They came out a 60" big screen television and they were the only things I could salvage out of it. I'm wondering if anyone has any cool ideas for them.

AFAIR, there are several things you need.

1.) A working LCD panel from which you can remove the backlight and not bust anything.
2.) A source of bright light
3.) TWO fresnel lenses, to collimate the source, pass it through the panel and decollimate it for the projector lens
4.) A projector lens, which I am presuming you have !
