Some interesting things I bookmarked on del.icio.us on October 21st, 2007:

• levelHead - levelHead is a spatial memory game by Julian Oliver. It uses a cube - with an image on each face - as its only interface.
• Best guitar solo ever - That is, If Ozzy would quit clapping … (^_^)
• Van Halen: recorded Jump goof at concert - So what happens when you?re Van Halen, the last song in your set list is the million-seller ?Jump? with its synthesizer-keyboard opening?and the recording you?re using to play back the synth is accidentally run at 48K instead of 44.1K?
• The Melloman - DIY Mellotron - The Melloman uses Walkmans and cassette tapes to play original Mellotron samples, or whatever cassette tapes you want to put in.
