Lately I came across JSFiddle a nice sandboxing tool to play with JS, HTML and CSS.
The approach is very simple and intuitive. You have your page divided in four areas one for each part of your fiddle and the last for the result.

the interface
The interface offers handy keyboard shortcuts to speed up the development.
It supports plenty of frameworks as MooTools, jQuery and Processing as well as the possibility to test AJAX and import external resources.
You should definitely give it a try. It’s worthy and funny (at least if you find funny this kind of stuff :รพ)
Amazing HTML5 procedural canvas-drawing example.
Completely written in HTML5 & JS it’s a funny toy to play with and a good showcase of the possibilities offered by the new standard.
Looking forward for a wide implementation (along with CSS3 specs).
