Phil has written up the visit that he and Matt made to a symposium by The Mars Society yesterday.
BTW – apologies for the lack of posts on interaction design/IA lately – it’s just that I’m finding it all a bit dull at the moment, and the wider world of science and design more inspiring… hope you all don’t mind…

it’s all to do with design anyway innit – there is no point to IA/UX design without “the wider world” (of science or design or whatever) … personally i find UXD (hmmm … “Danger UXD” t-shirts anyone?)fascinating *because of* these connections and analogues. these tangents and ‘bigger pictures’ are inspiring. keep it coming!
