This year a similar challenge has been set by Jean Stevens, here are the rules (they are very simple) basically draw a picture and share it on Twitter with the hash tag #DrawingAugust.
There are over 125 participating artists, so at the end of the month there will probably be about 3000 drawings to be viewed here.
I had a busy day yesterday, so I ended up taking my sketchbook and a pen with me to a performance of Richard III in the garden of St John's College Cambridge. I had 15 minutes between eating my picnic supper and the performance beginning, to take out my pen, do a quick sketch then pack up and take my seat.
This is what I drew:
