This congress is something really intellectual. So I used typography, cut it in half and turned the letters in different positions . This way you can find the letters or see it as a picture. It makes the icon a little abstract which is good for people having phantasy (for creatives like the members of the community etc.).
I chose strong colors to make it young and easy to design for the future. Since it is a very constant design, all colors go with the font very well.
For the next years colors can be changed. So the "Better Beta" and the year always changes (like the congress) but the design community will stay together (always one color (grey or white)). This way you don't have a polarizing image but a simple dynamic lettering.
The animation includes pictures and electric sounds to visualize the images "thinking", "community" and "conference" like a sudden inspiration which makes your brains electrons move. :)
