I was flicking through a coffee table book about Sicily yesterday and saw a picture of some outdoor paving in blue and white.The paving had a wonderful optical illusion of diamonds that seemed to appear and disappear before your eyes. I looked more closely and realised – those are half square triangles. The next question was of course: How did they do that?
For me the only way of working that out was to make some half square triangles in paper and lay them out on the floor.
I made up a sheet of six ‘blocks’, printed them out, cut them apart and had a go. You can have a go, too, by printing out the attached files.
I am looking forward to playing with them to see how many patterns I can come up with. I’m sure many others have done this before me, but it’s new to me and it’s fun.
