(OK - so not technically made with HST, but you start with HSTs and cut them in half to get hour glasses! Plus I NEEDED to have an image.)
I just saw this amazing short film by the NFB (National Film Board of Canada) that animates some of the amazing patterns that can be made with traditional blocks. It's like watching a kaleidoscope, but with quilting synapses firing! Whoa man! Funnily enough, it's simply called Quilt.You should watch it if you are spatially dim (but otherwise lovely) like me! You could also watch if you just want to be inspired by some pretty shapes and patterns. Y'know the stacked cubes in traditional quilts??? Made from diamond shapes! I know...AMAZING right??
