Why, my latest project of course!
Take 2 plain MALMA mirrors --2.99ea. at Ikea (okay, I got mine at Goodwill for 99 cents).
Take 1 old JENGA game -- Actual retail price -

? (again, got mine at Goodwill for 1.99 and the kids NEVER played it)
Paint the pieces, and the frame of the mirror if needed (the ones I got were the bright red ones, so the color pallete didn't go)
Hot glue on in a pleasing pattern, and hang.
Painting mirrors is a pain! The first one I did I taped then painted, and when I pulled off the tape, you could still see the RED reflected in the mirror, so the second one I didn't tape at all, and I sort of smooshed the paint under the edge of the frame where the mirror was. No reflection, but now I have to scrape the paint off the mirror. But whatever works for you. No pressure.
Finished project:

Photographing mirrors is hard too - you always get that annoying glare!!
