I would love to see a virtual reality app that plays with different organism layouts, and solving the usability issues.

There is a lot of great sci-fi that tries to consider how a world would be designed for non-humanoids, or mixed aliens, or the reverse archaeological problem of calculating how aliens look from what they have left behind. I am struggling to think of any sci-fi that makes you deeply think about usability.
