I'm calling it ASCII Tower Defence, and It seems like quite a nice little project I could work on on the side of all the school-work and revision I'm going to be doing over the next few months.
Although it doesn't really look like much in the mock-up, it should be a lot more appealing when moving, and when the design is a bit more final.
As a little aside about the mock-up: I designed it in the wonderful ASCII graphics programme ASCII Paint written by TIGSource forum member Melly. Try it sometime, Its great!
