The gear one was easy to implement, it is just a case of deciding the position 
and speed of turning. Because tiny angle changes are easily visible on gears 
(the teeth are not aligned) there must be a massive number of rotated images 
stored in memory (360 works well). The other problem is that because there is a 
directional shade across the gear image I used, it looks a bit naff when that 
shade then rotates and the shades of the different gears are at different angles.

The solar one on the other hand is rather difficult to make. Animating the 
flares is quite hard but I think I should have something to show quite soon.

When is the theme decided?
Are there licensing problems of including cc-by artwork into gpl projects?
