alt-J (∆) Breezeblocks

I like the tune and the video, even though there doesn't appear to be any direct connection between the two, other than perhaps the jilted lover syndrome. The video is reminiscent of Memento in that it happens in reverse order. The tune is just life, there's no violence in it.

How do you get a delta symbol out of Alt-J? By using a Mac. There might be a way do it on a Chromebook besides using cut and paste but I have yet to figure it out.
