I remember hearing about this DVD while it was still in progress. I just found out that it is now available.
If you are interested, you can buy it from the filmmaker's website (Catbird?) or by it from here:
I am not a super computer savvy person, but the DVD from the Catbird site is in PAL format which plays well on European DVD players, and reportedly also plays on most computer DVD players (regardless of country). If purchased from the Working Sheepdog website, you can choose which format you prefer - PAL or NTsomethingsomething (which plays on USA, Japan and Canada? DVD players).
I ordered mine from the Working Sheepdog website.
Disclaimer: I have no connection with either site/company.
