This is one that’s been sat on my hard disk for years, and I’m uploading it partly to supply it to someone on cix who’s asking for a higher quality version.
So there’s a streamed version from the good people at Youtube, and a better one that’s linked to below which you can download and view at a higher resolution.
As for the video – well what I can say, but it’s just a case of what those crazy Polish engineers get up to when nobody’s watching.
