Congrats for being the first to submit! Interesting approach with pie charts, it is funny but so far we were not working directly with pie charts, nor did we got any requests from client to develop such functionality even on reports, maybe it is where we need to go :-)
well thanks for your time... I'll leave them up for now...
at the moment I'm not really seeing anything at all that actually ties into what your product does?... that's kinda the thing that makes logos cool... I can't really give you any further input as I only develop logos if there is some conceptual relativity to tie into the brand itself... if not, then you can slap any of those "little pictures" next to any text and have a "company logo", kinda seems a little generic and random don't you think?
at any rate, avoid this stuff like the plague and you might come out squared away...
