I worked on a project in the early 1990s where we used the utterly wonderful HyperNeWS for most things - we used to play tricks on each other by doing silly things like logging into someone else's NeWS server using psh and setting the rotation in the transforms for a terminal window to be slightly off as people were using them - eventually people would notice of course but things would just work. Another neat trick that HyperNeWS supported was drawing a shape in its graphical editor and then pasting that shape as the shape of a window...
