Chello used to be a local ISP that IIRC got gobbled up by UPC, or at least so I remember; the German Wikipedia is IMO a bit hazy here and implies that it might have been a UPC subsidiary to begin with. The first time I heard about Chello was when I was in high school and they just gobbled up a local ISP, inode.at. But none of that matters now anyway, since it was all part of UPC, which for couple years now is part of T-mobile, *ehem* "Magenta", sorry. The whole consolidation of small, local ISPs into huge, international ones over the last decades is kind of crazy to think about.
The website itself seems to contain a list of mostly MS-paint style drawings of scientific, engineering and pseudo-scientific concepts (there are 3 lists devoted to perpetual motion machines), also I have no idea why graphene and "UFO over Vienna" are listed under "Centrifugal Force". Most of the stuff on the site also feels vaguely familiar, probably from some German phpBB bards I was on at the time. I'm pretty sure some of the weirder stuff reference old in-jokes that I forgot about by now. Stumbling over chello.at and GW-BASIC sure brings back some memories.
