I think the little icon on the spiral middle left is a clock or stopwatch, the bigger one (top middle, that looks like an eyeball) is a bug of some sort Bugdom 2 perhaps?
The circles appear merely to hold the tiny app clues, they aren't part of it IMHO.
Anyone make something of this?
[EDIT: Bugdom 2 was apparently an option in MH1 so not going to be here)
