So I have spent some time on Jokaydia Grid these days. Helping out a friend a bit. I was designing an obstacle course to be used by 3D course participants.
There are rings to fly through, there's a maze to explore, and a few other things to do. The ramps are to walk up, step on a disc, fly to another disc just to get used to maneuvering. There are even a few color changing scripts put in for some of these. Very cool!
