I'm working on two refinements of the fonts right now:
1.) I need to double check all the math and points locations for consistency of character height and stroke width, etc. The version I'm using right now has some inherited discrepancies in that regard (from resizing it several times) that cause some weird formatting issues every once in awhile. Not catastrophic, but could be better. I plan to apply these fixes to the latest versions of the font already uploaded to make it look cleaner and more consistent across the widest possible range of sizes, etc. I've also fixed some of the oddball characters with accents, umlauts, etc.
2.) I'm going back to the original logo images I can get my hands on and measuring the letter heights, widths and stroke sizes and will generate a new font based explicitly on these dimensions. The goal with this font would be to create a font that when the word "ANDROID" was presented in bold, it would look exactly like the official ANDROID logo, and all other letters would be consistent with those metrics. This will likely be a larger project and may not be all that useful on the phone for a daily driver font (so to speak).
Glad to see some folks are finding it fun/useful!
