Machinarium by Amanita Design is one of the coolest games I have ever seen. I love the look and texture, attention to details, and the soundtrack.
Give it a play the first 3 levels are free.
WINDOWSILL is an AMAZING cool game by the talented guys at Vector Park
An addictive, smart and fun kinetic game. BallDroppings ( excuse the name ) seems to be created in Java Script as opposed to Flash, which would have usually been used for this sort of thing.

This game looks awesome cool in a Tron, Starfox sort of way. Another reason to own one of these new i-Toys.
