After creating one of the logo options presented to the client in 3d, I couldn't help my self to animate it and show it as an enticing collateral if choosing that logo version.
I still believe the logo with only one cog and not two, is enough to bring home the message of problem solving. 2 cogs only repeats the same thing, and in the design practice of removing that is is not necessary, i see the 2nd cog as unnecessary.
