Sketchpad
Sketchpad is pretty impressive for an application built on Javascript and HTML 5. It really speaks to the complexity achievable in web applications.
From what I can tell, Sketchpad is a demo for some sort of online photo-manipulation app called Mugtug. While probably not as sophisticated as Photoshop, it’ll be great for basic cropping and resizing, especially if you’re running a “slim” operating system like that on the iPhone or iPad.
