BLU at Tate Modern, Listening Post at Science Museum

Ok-- a little fun is permitted.
I just made it down to the Thames last weekend to have a look at the Tate Modern's "streetart" pieces and I was surprised to see a gorgeous one by BLU, the guy I just blogged about a month ago. Go and have a look at it if you can. The exhibition is on until the end of august.
Another thing I watched again is the Listening Post at the Science Museum in South Kensington, a huge audiovisual installation which displays and acoustically synthesizes live snippets from chatrooms and message boards on the internet. There are videos on the internet but they don't come close to reality.
