Image Triangulation Tools

I want to share today's discovery - two online tools (triangulation tools) where an ordinary image or photograph can be transformed into a stylised drawing, in which all colour and shading areas are split into larger and smaller triangles while preserving the overall image. Computer graphics artists usually draw such stylised images, posters or website elements in graphics programmes, which is why the results look time-consuming, considered and of much higher quality. But for now, an entirely amateur approach suffices for me - upload the chosen photo and adjust the level of detail using the tool.

The first tool HERE is, in my view, the simplest and easiest to use. The images below were created with this tool. Hmm, it seems black-and-white images have a special charm.

The second HERE is more nuanced, but the image loading and transformation time is longer and more irritating for an impatient user.
