Affordances

pink guitars
As a relaxing activity I decided I’d restring my guitar. The pegs by the bridge are a bit stiff, so I used a biro to winkle them out. Of course, that got me thinking about the affordances of writing tools. The humble biro, good for poking holes in things, picking your ear and as an instrument of self-defence. And, as schoolchildren discovered, the casing makes an excellent pea-shooter. You can’t use a keyboard for any of this (well, I suppose you just could use one for self defence) - in fact it seems that the affordances of a keyboard are more limited….but I guess it compensates for this in terms of functionality (words, windows, images, sound etc).
