Seems you've created primitives with textures. Instead of a platform, build a walled garden to prevent players falling off and put a building (like a museum in the center) and show off your objects and scripts.
There are a couple of examples of art collabs that have used a museum type deal to show off participant's work. Outside of NewGrounds on SecondLife there is something called "Tower of Primitives" that showcased LindenLab's work. Consider taking a look.
