No, I am not talking about Swarowski. Just a nice 2D tiling with hearts to celebrate V Day (belatedly). I created this as a followup to Fractal Valentine using Escher Web Sketch, an online tessellation resource. It is hours of fun and a good way to teach and learn (or re-learn, as in my case) space groups and suchlike.
On a personal note, I was introduced to MC Escher by Prof. Rajesh Prasad (then IT-BHU, now IIT-D) who used to to teach us symmetry elements via Escher’s tessellations – lizards and fish and geese and dolphins and what not. One of the most enjoyable classes I had as an undergrad student.
So, any guesses on the 2D space group of this tiling?
