This one was done just before I left my room in Gothenburg to go home over Christmas. It was a bit stressful as I wasn’t bringing any machine with the right software to continue working on it with me, but luckily I managed to figure out how to make it work and got it finished the night before leaving :) Interestingly, I believe the red part of this illusion is actually possible, the first design didn’t have the different lanes but was a single solid object as the line version will show.

Linework | Fillwork
This construction consists of multiple vertical connections between bars that are perpendicular to each other.

This one is very cool!
Yeah.
Somehow, the fillwork works better than the linework.
Maybe the inner/outer conflict of perspectives is more exciting than a self-referential conflict.
Very interesting and very cool.
