I like the style of the designs in the #72, 75,114,115
and I was wondering if maybe you could try them with some tweaks to the purple , to go a little more to the violet colour and then balance the green with the new purple/violet?
Also if you could take a look at the latest general post about some other colour option combinations? it might give some more ideas?
I think I am looking for a logo that can have to words stripped out leaving a strongly identifiable icon / image for use with twitter or big simple image type branding.
