/* Munching squares, generalized to TrueColor. */
#include <yeso.h>
int main()
{
ywin w = yw_open("munching squares", yp_p(1024, 1024), "");
for (int t = 0;; t++) {
ypic fb = yw_frame(w);
for (int y = 0; y < fb.size.y; y++) {
ypix *p = yp_line(fb, y);
for (int x = 0; x < fb.size.x; x++) p[x] = (t & 1023) - ((x ^ y) & 1023);
}
yw_flip(w);
}

I think that, in terms of accessibility, these 14 lines of C compare favorably to the 15 instructions (and one assembler directive) in the 31-byte mode-X demo Klappquadrat, for example. Yeso also has Lua and Python bindings, which are somewhat incomplete. I haven't written Pascal bindings

for it yet, but feel free.
On the other hand, that won't give you the same kind of satori experience as the bare-metal C64 experience, because Yeso is running on top of some arbitrary stack of software you don't understand, and the C64 VIC (or VGA mode 13h, at least if you're using a real VGA) is really just circuits. Using Yeso won't stop you from feeling that what's behind the library calls is magic.
