I Stumbled across this site and thought that it was mind-blowing.
The page is split into two equal horizontal sections which are separated by a movable divider.

Not only that but your existing code can be copied and pasted into the top section with immediate results displaying in the lower section!

I’m off to check the other goodies on offer:)
