This is really not interesting.
rep_concat: 64,64,1,1,"begin(concat(a,b)=b+a*10^(ceil(log10(b+1))+ceil(abs(b-.5))-b););px=abs(x-32);py=abs(y-32);q=int(norm(px,py));p=max(px,py);concat(p,q)%128;"
This basically utilize concatenate two integer number.
I got this idea from a blog that I can’t seem to find anymore which utilize concatenation, but the person didn’t made this sort of result with it, but something else.
EDIT:
With 31, it’d look like this:
And can also do this with concat(a,b):
Edit: I found the blog - Concatenations — Kerry Mitchell
That is where I got this idea. I don’t understand it though.
