It is a dream board theme, can't remember the repo but you have to download the dream store. If you don't want dream board I don't know of any other iPad themes. Sorry
I'm also bored with the stock springboard and have been looking through Cydia. Dreamboard is really unstable, at least for me so I looked at tons of Winterboard themes. The best one I've seen is Black Haze but it isn't free. At the moment I'm using "TouchitiPad" - it's not bad but I'm still looking.
