I can't do the black background and the ones with too many colors are distracting. I like the others, but my only concern is that the symbol is very similar to one that logostudio already submitted.
I like #154 and #155. there is only 7 hours left in the competitions, but we are very torn between the top 5. Can you submit an alteration of these two that takes into account orange? Perhaps as part of the folded 'M' portion?
