www.scrapblog.com : I’ve seen a lot of browser based flash ‘applications’ over the years – you know trying to emulate the desktop experience inside a web page… but few have cut the mustard. They tend to be slow, clunky, buggy and miss out on the detail such as keyboard shortcuts. Scrapblog (which you use to put photo albums together) is an exception to the norm and is really quite outstanding. Even CTRL-Z (undo) worked. Go play. Then you can order a 20 page hardback version for about US$35. Pretty good deal we thought.
Scrapblog has a very well executed Flash interface.

You’re right, they did a really good job.
BTW it’s a Flex application.
