We're honoured by the fact that the logo of the Design & Emotion conference is inspired by our logo. We think of it as an "impossible³" (cubed impossible), a three-dimensional impossible figure, represented by a two dimensional square.
When starting Room of Riddles, the laptop with design-tools broke down and hence we needed to find a workaround to design the logo. We hence sketched the logo in, hold your breath...Powerpoint! After the draft was done, a friend of us actually rebuild it in Illustrator to make the files required for the printer.
We got many compliments about our logo so far, but this contribution by an international conference might be the best!
