Yeah! Several in fact—I have enough concepts to fill multiple exhibitions, and that's the dream, so I just need to make them now. Currently working on the PCB for my first one, which will ideally be purchasable too. I'll keep quiet on the description for now though, but they're all weird.
Oh cool, just looked them up—they’re slick! And funnily enough one of the demo images is a 7-segment display. I love the ~skeumorphism of things pretending to be more constrained than they are and I've seen a good few examples specifically of more expressive displays using the 7seg design!

You have any end design in mind?
