A doom engine. Actually this is more exciting than it sounds, because I wrote it in 1996 before ID software released the source for doom. DUMB also uses a different algorithm for the 3D rendering, not the BSP algorithm that ID used. DUMB’s algorithm allows vertices to move. so in principle it could have had doors that opened sideways (you’ll recall that doom’s doors always shot up into the ceiling or floor).
Until September 2016 I am a Tutorial Fellow in Philosophy at Corpus Christi College and an Associate Professor in the Oxford Philosophy Faculty. From then on, I'll be a Senior Adviser at the New Zealand Ministry of Transport.
My intellectual interests are mainly in metaphysics, philosophy of language, and ethics, and of course transport policy.
