I've now added a ScratchPad for Squiffy, like the one I added the other day for QuestKit...

http://docs.textadventures.co.uk/squiffy/scratchpad/

It lets you play around with Squiffy without having to download anything.

I'll be updating the documentation to include more "live" examples, like the one I just added to the Squiffy documentation homepage http://docs.textadventures.co.uk/squiffy/. These will also include the "Edit in ScratchPad" links, so you'll be able to play around easily with all the examples.
