Interesting! I've included this submission in Post #2 of this thread.
I like the big logo on the back though we need to start using the Ƀ symbol.
I like the orange Bitcoin logo more than the Ƀ.. or even just "BTC".. but then again T-Shirts might be the place to switch it up.
Is the Ƀ symbol official? http://en.wikipedia.org/wiki/B_with_stroke

B with stroke (majuscule: Ƀ, minuscule: ƀ) is a letter of the Latin alphabet, formed from B with the addition of a bar, which can be through either the ascender or the bowl. It is used as a phonetic symbol to represent to transcribe the sound [β].
⟨Ƀ⟩ is also a letter of the alphabets of the Jarai and Katu languages of Vietnam, and is used in standardized texts in Old Saxon as well as in reconstructed forms of Proto-Germanic
The letter Ƀ has also been used as part of a proposed alternative symbol for the Bitcoin digital currency [1]
