HyperSpace - TIC-80 128 bytes

Perhaps my favorite due to binary size and result, very similar technically to Apollonian but drawn differently.

I remember struggling with many things on this one because i wanted to reach 128 bytes with interesting sounds and not just background buzzing likes Chmmr.

It is a Minsky circle variant but moving from top to bottom with circles oscillating in size, i was going to clear the screen at first but i was not satisfied at how it looked like so i made the decision to not clear the screen, this surprisingly provided a much richer picture which seems multidimensional; glimpse of structures fading in and out over time.

The code is LUA and is packed with pactic.

I also did a quick DOS port for this one without colors and sounds to see how small it can be on early CPU / 80s platforms, got it under 100 bytes, could probably go lower (64b ?) perhaps but got bored in the process.

Unpacked version :

x=1

y=0

cls()

function TIC()

for i=0,1e4 do

t=time()

x=x-y/2+t

y=(y+x/2)%16384

x=x-y/2+t

t=t//8

poke(65455+y%64,32+t%64)

pix(x//128+120&255,y//128%140,t//33+i//8e3)

end

end
