Web Design

Hahlo.com

Created by Dean Robinson, a Web developer at Australia's University of Newcastle, Hahlo is a sleek iPhone-optimized interface for Twitter. Robinson aimed to "provide as much of the Twitter.com functionality as possible, in an interface that is as easy to use as it is on the eyes." Some smart elements of the usability design: enlarged buttons (big enough for a finger to tap), and a font, Helvetica, that's easy to read even at small sizes. (Bonus: Helvetica is the font used in native Apple apps on the iPhone.)
