I'll be honest...I've never cared much what the wallets look like as long as everything is easy to read. Perhaps some do care...and the effort to change the look here is commendable...but how often are you really staring at your crypto wallet?
While I will admit I like the Megacoin client...it has more to do with the layout and ability to easily see transaction history from the main tab than it does the actual design. Thus far, it's the only wallet I've seen that (arguably) improves on the default design. The color scheme/etc is neutral to me.
Colors/crazy fonts/etc don't really interest me. This reminds me of the old "Sub7" and "NetBUS" days.
