You reached a Web page of Dr. Igor Muttik on CARO Web site.
I spent quite some time researching macro viruses and
related file formats so a picture on a street in Venice
called “Calle de le OLE” seemed appropriate here 
And here is a picture of some (not all) CAROids taken in Hamburg in 2003. I am in the bottom row in white t-shirt on the right.
Upper row, from the left: Katrin, Eugene, Peter, Righard, Fridrik, Nick, Klaus, Costin.
Bottom row: Vesselin, Peter, Kurt, Jimmy, Igor, Mikko.
