I have two of his original drawings/paintings here at home on my wall. I live in Lund, which he also did for a while, so it’s pretty common to find them in art stores and auctions for pretty cheap.
I had some print or poster on my wall in my childhood bedroom in Stockholm. For sure no original but reproductions were, as I remember it, readily available when I grew up.
I love Eschers works. A few years ago I watched an documentary about his in the cinema, but I can remember the name.
3Blue1Brown just released an amazing video explaining the geometric transformation for Eschers print gallery. This made me try to reimplement the effect as WebGL shader [1].
It was very much fun especially doing it fully on my own just based on the general idea without looking at actual existing implementations. It highlighted for me how in non-linear transformations even small mistakes on my side can have huge negative effects on the final image that are tricky to pin down due to the non-linearity.
