'Really powerful': Banksy's animal murals get Londoners speculating

One goat, two elephants, three monkeys -- Banksy's latest artworks, emerging across London these past six days, have prompted a range of interpretations, from commentary on Gaza, or the recent UK riots, even the Olympics.

One of the pieces, a howling wolf painted on a satellite dish, is believed to have been stolen within hours.

"The symbolism of it is really powerful," says Jason Tomkins, one Banksy fan.
