when i was in IT class me and a friend created a backdoor/trojan similar to sub7, but as a remote admin tool, (using visual basic!!) to learn more on the subject. it was a class project but we kept going. (btw no i wont post it caz theres enuf on them already) but we did all the usual stuff including a good little gimmick that send an encoded winpopup message through our servers to all the computer (on our network) with the ip in it saying its online and so on.
But we did also do the flip screen, open cd rom thing, but only because we could.
I mean if its there and fun can be had, why not?
