IC3 or IC-DreiLogo Design Contest

...sei dabei! (which means "take part")

IC3 is above all a searchengine and catalogue for products and services in Germany that gets paid by retailers for sending them shoppers. IC3 (or IC-Drei which is more the URL) gives a part of that money back to their users (registered members) in form of "cashback". See also the existing website http://www.ic-drei.de which will be redesigned on base of the new logo.

Red and blue (like the existing logo) is preferred. But other colours are welcome if you argument with some reason.

Some kind of competitors are (not all because of their markets, but same business model):
