SiL is a 3D puzzler by Fathammer Games, also the developer of the freeware vertical shooter entitled Angelfish. The game involves rotating 3D objects to match their silhouettes in the background before time runs out, hence it's chosen name.
Unfortunately this production runs out of steam rather quickly even with over a hundred different items and wonderfully crafted locations.
