Ok, I played with Apple’s Dashcode for about 5 minutes. In that time I was able to create 2 widgets, one that displayed a text RSS feed, and one that displayed a “Photocast” feed (an RSS feed with image enclosures.)
This thing is powerful… I’ve built widgets before, but it always involved mucking around with a lot of code. Dashcode is seriously drag ‘n drop simple. Any novice computer user could create a widget.
I can’t wait to start building some little custom apps with it. (It’s a shame it’s OSX only… well, there’s always Yahoo! Widgets, right?)
