I found this installation (2012/04/23-28) by Okawa Mamiko (大川真美子) at Gallery Hinoki (ギャラリー檜) to be quite interesting. Shadows from overhead prints hanging within a projector beam combined with projected shadows moving mysteriously across the wall... it was fun/intriguing to experience. この影のインストレーションは、凄く面白いと思いました!
