There was a thread on here a few months back about trying to find the film Stonnis online:

It wasn't available a the time, but I had an email from Mike Cheque this week to let me know he'd got it back online at Vimeo.
Just posting it again for anyone who was interested, it's a fantastic film and well worth watching if you missed it when it was on BMC TV
