In the "smiley" logo I personally (and as a CEO ;-) would like to avoid the smiley element, in general. I know it looks very attractive and funny; however the smiley is a registered trademark sign, and we don't want to have problems with the law. So either we would need to present a smiley like it would not cross with the smiley definition from the trademark, either we would need to create something pure fresh.
Ok... from the working tapes of miniBB team :-) Below presented the list of all of our imaginary within the past year. Don't consider them as the final versions still.
In the two examples above, we supposed to try to make a logo in the "corona" form. Later, we have denied the corona symbol, since nobody from us is the king.
As you may notice, the wording "miniBB" is very symmetrical. It contains horizontal, vertical and the diagonal symmetries. The first example above just shows it, the second pretends to build a logo full of colors on this principle.
Above comes just yesterday's example. Very tough draft, but the idea here is the wording "BB" appears to be a mirrored shadow of "mini", like it would appear from the sun raising in the background. Overall it also gives an ultimate 3D effect to the board.
Above is just a funny example of how Zooropa logo from U2 fits to miniBB's older concept ;-)
