After implementing multitasking and adding a small clock in the right top corner, all sorts of weird stuff started happening, like this.

That's jazzy as heck. More, please! I want a wallpaper like that.

Testing a rectangle drawing function I wrote in assembly with different resolutions, not what I was expecting but it's a modern abstractionist masterpiece and I want to tour with it to galleries worldwide, schmoozing & sipping fine wines that taste like anti-freeze if I can get the expenses paid for 8)

Implemented some maths functions to my kernel's runtime library because I want cool graphics stuff, so tested out some pixel plotting, and a couple famous line and ellipse drawing algorithms. Everything works but I gave some off parameters and got this! Want to become good with the graphics/mathematical side of things 8)

Well, that looks fine to me, if you goal was to depict a Mobius strip. I gather it wasn't, however.

Not even Rust is immune to undefined behaviour.

Don't worry! There are enough smiley faces and hearts to solve this.

Not really going crazy, and it's actually expected behavior, but crashing nonetheless. I am currently porting my compiler/VM to my OS to provide a user-mode programming language. Here you can see it come to life.

What happened is the VM crashed because of an unimplemented opcode, which resulted in the VM trying to drop its hosting task. However, my proof-of-concept implementation is running it in the kernel task, which is "immortal" (can't be dropped). The result is that the CPU continues executing garbage and eventually raises an interrupt.
