Reasons to - Remix - I
license: mit
height: 875

The speakers for the wonderful 'Reasons to' conference in Brighton are asked to create their own "remix" of the logo (you can see the current collection here). Because I was fortunate enough to win the "Elevator Pitch" last year I am coming back in 2017 to do a full talk and thus was also asked to create my remix. Well, pretty obvious to me that I had to do something with hexagons and rainbows ;)
