Personally I haven't, but I can't imagine it working well. If you're talking about cork tape I would feel a little iffy about putting it on the grips, it would get dirty, start to flake off, and need to be replaced regularly. The more rubbery tape like Fizik tape would be okay, but I don't know if it would be as grippy as I'd like it to be. I think a few bikes on BikeExif have been done up with leather tape, which looks nice but I don't know if I'd want it on a daily runner personally.
