as @tml and @photovince rightly guessed, I had the opportunity to visit a #strandbeest session today. For those not familiar with them, have a look at strandbeest.com or look it up on wikipedia. Reservations need to be made way in advance, so I was happy that there was enough wind but not too much to see the beests in action. A brilliant session with a group of 30-50 people, lots of explanation and some hands-on work as well. Will do again! (Videos posted in reply to this post)
