actually this is the only one i like so far. its simple and yet professional. not overloaded with lensflare, glow or any other weird filters o_O
i don't really like the definition of the bulb (the thing under the C). with some refinement (also of the proportions) it could become a nice logo though.
...and is this a logo contest or a splash screen contest? a logo and a splash screen are two different things...
