This was my first concept for an OFLB logo. The idea is that many fonts may incrementally emerge through the remixing process, and I wanted to reflect that in the logo. I used a range of geometric shapes rather than actual glyphs to create this logo. I previously tried red and green-yellow colour schemes, but a previous comment said the red was too much like the Opera logo (I didn't see this myself, but agree) and the green was a bit too energetic. I like the blues in the Tango palette included in recent Inkscape builds, which is what I've used throughout. I am using the pure form of the O because I feel this is the most beautiful form of those in the OFLB acronym.
