Over the past few weeks, I've been experimenting with painting in watercolours using my AxiDraw plotter. Watercolour is a medium I enjoy painting in (by hand) as a personal hobby, kind of separate from my public art making, so it’s been interesting to combine it with code. I’ve thought about trying

If you’ve done any 3D programming, you’ve likely encountered the zoo of techniques and representations used when working with 3D rotations. Some of them are better than others, depending on the situation. Based on CMU 15-462 course materials by Keenan Crane. Representations Rotation Matrices Euler Angles Quaternions Axis/Angle The Exponential and Logarithmic Maps Axis/Angle in 2D Axis/Angle in 3D Averaging Rotations Quaternions (Again) Further Reading Representations Rotation Matrices Linear-algebra-wise, the most straightforward representation is an orthonormal 3x3 matrix (with positive determinant). The three columns of a rotation matrix specify where the x, y, and z axes end up after the rotation. Rotation matrices are particularly useful for transforming points: just multiply! Even better, rotation matrices can be composed with any other linear transformations via matrix multiplication. That’s why we use rotation matrices…

I love learning something that flips my head upside down. So, let’s look at one of the coolest head-flippers I’ve found: Japanese addresses.

An interview with renowned Italian film director Manolo Luppichini highlights grassroots efforts in Gaza to counter communication blockades using simple technologies like ”Web Trees,“ addressing global double standards and resistance of cultural genocide.
