Design a Custom Character for an LCD

First off - this is not my original design.
Bruno Maia / Icontexto.com built this originally. It's been a very useful tool, but in recent months, it's disappeared. I thought I'd just make a quickie re-build of it, so I copied the graphics from a saved screenshot and wrote some simple-minded Javascript to design the Custom Characters and emit Arduino Sourcecode for the LiquidCrystal library.

I believe Internet Explorer renders the Sketch Code indifferently, but the code is correct.
