Emacs create cursor

view story

http://unix.stackexchange.com – Is there a way to create an additional "dummy" cursor in Emacs (preferably multiple)? Ideally I'd like to be able to set its color separately from the original cursor and set its position. Then I'd have the regular cursor that behaves normally, and I'd have multiple extra cursors whose position has to be set by some other means. (HowTos)
