Special

The special toolbar is sort of like the 'junk drawer' of Grasshopper. On one hand it contains things you use all the time (i.e. Number Slider or Panel), and on the other hand it has some components that are more or less just for fun (Random LolCats or Image Gallery). Other customizing components include multiple color, graphing, and file/image import options.

It's worth giving it a browse from time to time, because you never know what you'll find that will be exactly what you need to spice up your definition!
