It was released mid-2009, and Lazy 8 Studios seems to be quite at work with the release for the iPhone. The PC version is available at $9.99 with a free demo to check out the gameplay, and it should be described as a mix of puzzles, from Pipe Mania to Bryan Mitchell's Geared.
Cogs should be with us next year, as in early 2010, and published by the infamous Chillingo. The final version will contain 50 levels across 3 gameplay modes, along with a boasting of being a "polygon-pusher". While the screenshots seem to back up these claims, we hope performance issues don't ensue on the older generation devices.
