Examples of good functional design in the digital space (as opposed to good ways of making existing ideas look nicer), are so damn hard to find these days. It follows that good designers are also very rare. So thank heaven for Aza Raskin, scion of the late great Jeff Raskin, designer of Firefox mobile, and Creative Lead for Firefox. Aza consistently produces real, solidly innovative, and actually useful designs that solve problems. Here he is with an evolution of the “zui” to deliver TabCandy, a very nice idea to improve the way you use Firefox.
As an aside, Aza’s work also makes MSIE’s “designers” look like a total bunch of muppets. There are probably hundreds of them to his one, yet they couldn’t think up anything new or interesting if they swung from trees made of fruit loops.
