Lukas notes the Len Lye movie being shown in Auckland at the moment... if you really want to see some cool Len Lye stuff the New Plymouth Govett Brewster Art Gallery is the place. They have some truely phenomenal kinetic sculptures from the man who must surely be the grand master of that art. A photo simply does not do Trilogy (below) justice...

[UPDATE] In case you haven't seen it the above sculpture is about 10 meters high and hangs from the ceiling of the art gallery.... when running the sound alone is truely awe inspiring... and quite frightening!
