Buy a box of 6 mirror tiles ( i.e. something like this )
Use some duct-tape and make a box out of them (mirror-side inwards)
(put a little duct-tape handle on the 6th tile to make it easy to take it on and off)
Set timer on camera, (turn flash on), place camera in box, put mirror ‘lid’ onto box before shutter fires…
…get cool photo.
toss in balls of aluminum foil – because they’re shiny.
Play with light-leaks at the seams of the box.
Add candles. Pretty.
Finally, add Droids. Everything is better with Droids.

UPDATE: Here’s someone who got inspired about the idea and did a MirrorBox photo-a-day of throughout January 2012 http://flic.kr/s/aHsjxK8ZKe Cool!
