Nowadays, the main challenge of designing software is neither in building an efficient database structure, or getting the functionality right – it is all about making it accessible to a multitude of users, whom may be interacting with the software in a number of different context – from a desktop computer at home, from an iPhone commuting on a train or maybe even through some embedded device?

Bret Victor, who among many other things is a former Apple interface designer, manages to design amazingly impressive and intuitive interfaces which communicates effortlessly with the user.
