Nevertheless, it was a great time with lots of fun. On day four, Tigerduck and I played a few rounds of Robix (by Raster) and Scorch (by Pirx and the team). And ultimately, with the support from the guys from Pigwa, my video tutorials are now all also available there for download - just in case youtube goes down one day :-)
Thanks to everybody who participated; this was a lot of fun. See you at Fujiama!
