To be honest I find that commercial merely annoying. As for genuinely trippy commercials, may I suggest >this;. I've seen weirder, but I can't find them offhand.
EDIT: I was referring to the original post in my post. The Pickle Surprise one is pretty good.
First thing that came to my mind was Sprite's "sublymonal" ad campaign, especially the "">spa". Zune Arts also had some nice ones. My favorites are the ones with the ">masks and ">bears.
