Existing open source software library seeks logo.
Most intended uses would be in a square display, i.e. as an icon.
I maintain an open source software utility that has been around for ages, but I've always lacked the design skills to give it a unique logo, just using whatever default has been substituted. Library is "Dapper", which is a software library for communicating with databases.
Possible design elements:
- could play on the "databases" theme (lots of prior art and themes there)
- could play on the "dapper" theme (https://www.merriam-webster.com/dictionary/dapper)
- or could ignore both and just go for something striking, recognizable, and unique
Logo text ("Dapper") cited in the brief is strictly optional.
There is no "company", "brand" etc to maintain - just wanting to make something prettier
