A colorful generative composition made by subdividing the canvas into triangles and randomly subdividing them several times. The largest remaining triangles are yellow and they become green and then blue as they get smaller, the smallest ones are very dark blue. They follow the matplotlib Viridis colormap.

Another experiment with swirling particles getting smaller as the leave a trail from yellow to blue

@nrennie Great visualisation! Thank you, I like to show my students why I'm insisting on scales like the #viridis scales.

(for those wondering, the dichromat package does a great job at simulating different types of colorblindness)

Dear #RStats , I tend to use #ggplot2 for my plots and the #viridis color palette. However, if I need to print a poster, the printing services always change the palette to a #cmyk palette. Is there any way to use in #ggplot2 a #cmyk palette resembling #viridis ? Thanks!

random rectangles filled with a blue to yellow gradient made with the Viridis color map from matplotlib

I'm "strangely attracted" to these. Figures and video show (René) Thomas' attractor. For these visualizations, I set b=0.19 and initialized the orbits at z=1.
