Thanks HerDish, this is a great start! A couple of general observations: prefer the text under the TB (#2, #3, & #4). Like the idea of incorporating a smart phone device (#1), but it makes the TB hard to read. Like the idea of a 3D feel, but again it makes the TB a little harder to read. Prefer the font and treatment of #s 2-5.
These are all great, I like the smooth and rounded TB, but would also like to explore some that are a little blockier - to pick up on the "brick" idea - or a combination of blocky and curvy.
Thanks again, and keep up the great work!
