I'd like to write a script that will run when I log into OS X, which will do the following:

1) Launch Terminal
2) Immediately close the window that Terminal creates when it opens.
3) Preferably, keep Terminal hidden while all this is happening, so all I see is the Terminal icon bouncing in the dock as the program launches.

Any advice appreciated

PS: I'd prefer the script to be a .sh or a .c file (to compile), as those are the only two languages I have some experience in at the moment. Thanks.
