Before I went to the UK, the Hugo Boss window in Siam Paragon caught my eye. It reminds me of the kinetic installations that a peer on my fine art degree used to make. This window display didn't move, (can you imagine how fabulous it would have been if it could?) but, for anyone in Bangkok, there's a vast clockwork installation in the middle of Central Chit Lom that does move! (BAH; why didn't I take a picture when I was there yesterday?)
Using a light source to throw shadows is a simple idea but I imagine it's not as easy to execute as it looks.
