Scratch for Second Life

S4SL is a new easy way to add behaviors and interactivity to your objects in Second Life. S4SL is based on Scratch, a graphical programming language that lets you construct programs by snapping together graphical blocks.

With S4SL, you can snap together a few blocks to make your SL pet interact with you using chat commands, make your sculpture change size and color, or make your house respond to your presence.
