Those cogs cannot possibly move; if you look closely at how they should move, you can see that they are stuck for ever.

It may not be practical, but it is still an 'engaging' puzzle. Loved it.

Nice, but as KarinKnipping mentioned, it's a useless arrangement. You need an even number of gears in an 'closed loop' connection like this for it to work.

Nice picture, but the cogs can't rotate this way.
