I put this site together in about 40 minutes after finding the link on Stephen Downes daily mailing list.
Although fairly restricted at the moment, Prototype introduces some really fun features. I'm looking forward to the day when there may be a greater variety of panels available to include - and the opportunity to create multiple linked pages (ie create my own site)
As you'll note - I've played around with the HTML features which have allowed me to change font and incorporate pictures.
