Just a note that using PixieDust shows up as squares on my new MBP. They show up as Stars on all of my other Macs (Rev A MBP, Rev B MB, 12" PB G5 Quad w/7800GT, Core Duo mini's). I'm assuming this is an issue with the nVidia drivers and not OmniDazzle, but I thought I'd drop a note in here just in case.
