I came across https://ui-avatars.com, a web service that creates avatar images based on some parameters.
From Pharo, the shortest invocation would be something like
ZnEasy getPng: 'https://ui-avatars.com/api?name=Albert+Einstein&size=128&background=0D8ABC&c...'. Making use of the full builder interface of ZnClient that would look more like ZnClient new https; host: 'ui-avatars.com'; addPath: #api; queryAt: #name put: 'Albert Einstein'; queryAt: #size put: 128; queryAt: #color put: 'FFF'; queryAt: #background put: '0D8ABC'; queryAt: #rounded put: true; accept: ZnMimeType imagePng; enforceHttpSuccess: true; enforceAcceptContentType: true; contentReader: [ :entity | ImageReadWriter formFromStream: entity readStream ]; beOneShot; get. Anyway, it is cool to have an environment that makes this kind of experimentation so much fun. It is probably easy to implement this avatar image generation directly in Pharo ... Sven
