Chalk for iPad
37signals just introduced Chalk, a nifty little sketching tool for iPad. It’s a free web app, with no need to install through the App Store. Quite impressive what you can pull off with a little bit of HTML, CSS and Javascript these days. I particularly like how they leveraged the Canvas element to enable image saving in Safari for iPad – a clever workaround so they don’t have to deal with file storage and sharing features.
