In mist, all accounts have a colourful pixelated "profile picture" used to identify them. For instance, in this screenshot from the Mist releases page, the Dogecoin Bounty DAO is given a purple profile pic. How are these generated?
Our port has a few graphical fixes as well as a significant fix to avoid duplicate icons in the original version caused by a bad random number generator. The upstream author doesn't want to accept the good PR since it breaks existing icons for existing users, so for the foreseeable future, we'll use a fork and not the upstream lib.
