Dean programmed first on a TI-57, which was swiftly upgraded to a Sinclair ZX81. He sold two games for the Spectrum before heading off to Oxford, where he spent rather a long time to acquire his MA and DPhil in Natural Sciences. (It was here that he coaxed nitrogen to multiply-bond to uranium, apparently for the first time). At MultiModal, in Princeton, he headed up graphics, animation, and mapping solutions, and at Labs now he is still rather keen on all things graphical. He runs, bikes, drinks, codes, and plays the piano – some of them at the same time.
