An excellent course, very glad I purchased it and completed it. Well worth my time and money.
All my sketches (using the excellent canvas-sketch) are located in src/routes/ as js files. If you want to work with images, create an 'assets' folder there and replace the image filenames you see in sketch-05.js with your own.
Also added three more files created by fellow student ddddd, as seen in his final project.
I'm in the process of adapting these sketches into Svelte components in a Sveltekit build.
