Came across this polished little Java game, which IMO belongs in the featured section.

You are the Tetrobot: a tiny robot that can drill blocks of matter one by one, collect them, and recycle them into new pieces of 4 blocks. You also have the possibility to destroy lines of 8+ blocks in a very «retro russian» game style. Sand, wood, stone, obsidian, iron, diamond: each matter has its specific behaviour you’ll have to use wisely and take advantage of them. So get ready to use your brain and combine your platforming and puzzle-solving skills in this incredible mashup! <a href="http://www.youtube.com/v/Ekx80MnQug4" target="_blank">http://www.youtube.com/v/Ekx80MnQug4</a>

The game is available on Windows, Linux, Mac, Xbox Live, Steam, Desura, Indievania, etc.

A playable demo can be found here.

Also just learned that 'Blocks That Matter' was the winner of Microsofts Dream.Build.Play 2011 Challenge winning $40,000.00. It also uses LWJGL for the Windows, Mac and Linux versions.
