This clip from Harry Potter and the Half Blood Prince was aired at the MTV Movie Awards with a funny intro by Daniel Radcliffe, Rupert Grint, and Emma Watson.  In it we get to see the set up and beginning of the scene where Dumbledore and Harry Potter enter the Pensive to visit the memory of Dumbledore's first meeting with Tom Riddle.  I love the look of the Pensive.  Watch the clip below.
