Who did the street art on Center Street?

[Update, 05.25.11: Some street art is short-lived. The wheatpaste works shown here have already disappeared to be replaced by other ones. See the new works on the What I Saw in Berkeley blog.]

Here on Artside Berkeleyside, we have a soft spot for street art. Tina Zhu came across the most recent interesting examples on the enticingly plain walls of the old university printing plant on Center Street and Oxford (which, appropriately, will be the new site of the Berkeley Art Museum).

Do any readers know about the artist?

Not quite Banksy, but intriguing
