On the useful side we have tools such as a Particle System Generator, which allows users to fiddle with settings through a web-page interface and see these settings in action within Second Life using the associated object. We also have a range of sculpt texture generators which, as the name suggests, creates sculpt textures in this case using a series of parameters which are fed through some simple mathmatics to produce a solid 3d object specifically designed for Second Life's sculpted prims. The asthetic side of my experiments is dominated by my Flexi-hedra. These were born as geometric solids but evolved into living moving sculptures.
