ah damn! someone got it first.
Nope...he got only 1!
Okay then, I know he drew the Doctor Who weekly back in the 80's(?), WATCHMEN and Give me liberty
You've got two...you need a third that he co-created (as he didn't co-create Doctor Who)...Thinnnnkkk...he just finished something (hint hint).
ah... co-created... hahaha TREATMENT!
Wait, whoops--I just re-read the question--I asked for three OTHER than Treatment...and the project I was thinking of was something else he just finished that he co-created! (Sorry, I guess I forgot the exact question I asked!)
AHHHHH!
Try with "The originals" 
THERE WE GO! (He solely created Treatment, actually)...10 points are YOURS!
