Today's random book recommendation...

I picked up an excellent book last week at Octopus Books in Ottawa called Our Own Devices - how technology remakes humanity, by Edward Tenner. I've only just started reading it, but have already learnt more about shoelaces and walking gaits than I knew before. Reclining chairs, helmets and typewriters all come under the gaze of Tenner, as he examines blurry boundaries between technology and technique.
