The art sections seem to be for art pieces rather than general art discussion, so I placed the thread here.
I love where science and art intersect, either scientific endeavors that are art or art being applied for scientific purposes. Here is an example a series of works I love, art pieces made via X-rays.
X-Ray Art
I especially love the botanical pieces using this technique.
I also love fractal art, and complicated gears like the Antikythera mechanism and the Eisinga Planetarium.
