Knock'em all down!
Dominoze is a 3D puzzle game where you have to figure out how to knock down all the dominoes. It comes with numerous levels as well a complete editor for players to create and share their own puzzles with.
After nine years of rigorous development, the game was never finished due to many reasons which include product instability, poor planning, marketing and implementation. You can read more details on Gamasutra.com.
