This is the new logotype of Krakow Users Ruby Group. It’s composed of full name of the organization, and symbol including a ruby and Wawel Dragon, an identification attribute of Krakow.
The two other options were Lajkonik with a ruby (a Tatar man on a horse - an unofficial symbol of Krakow) and a ruby in a form of a ruby red hat with peacock feathers - an element of Krakow’s folk costume.
We are glad that my submission won and happy to be a part of our local community! We hope that printed t‑shirts will be worn with pride to be a programmer:)
