Most of these projects have been created while working for companies such as IDEO, Motorola, Sapient or in collaboration with other designers and clients. It is not only impossible to design all by yourself, it is actually terribly boring.
I have always been interested in exploring different design disciplines and different industries. So you can find here projects like Xerox's Interactive Showroom in New York, mobile phones for India or illustrations for children books.
I truly believe that old saying of 'design is design is design' you can borrow from one discipline and use on another, learn from one industry and apply it on a completely different one.
