This is still a work in progress. I'm pushing the new bricks, stacking and nudging to the limit to create some nice flowing shapes. This is also a great opportunity to get working with some good kerning. Once I have the basic character set, this is going to be submitted to Google Fonts for approval.
A funky idea that started with the A and expanded from there. Most letters are drawn by a single line winding around, although some are just not willing to follow this mantra.

There's an alternate, narrow set of numbers that can be reached with Shift+number (on a QWERTY, Dvorak, etc. layout); not sure which set fits the style better. Suggestions and critiques welcome for anything, and feel free to clone and poke around with it. Thanks and enjoy!
