@akkartik this is because privacy from *sites* is not the use case for incognito mode, privacy from other users of that computer is the use case

You could increase detail by adding terms of course, and this is the basic concept behind jpeg compression, where such an equation represents an 8x8 pixel block. there's nothing really new or novel about summing cosines.

So but, imagine it's the 1970s and you're doing this with big old boxes with patch boards and such. The neat part in my mind, is implementing the ifft using optics/lenses.

Toying with a video synth concept in desmos

So, my concept for this, (though not really illustrated here) is to generate video with the sum of two cosine waves: you can almost imagine analog circuitry for this, if you're a plug head:

Z(x,y,a,b,c,d,e,f,g,h,i,j,k) = a*cos(x*b + c)*cos(y*d + e) + f*cos(x*g + h)*cos(y*i+j) + k

(for each RGB channel)

and so using an ifft on some 2d image you could very blurrily approximate an arbitrary image- and "morph" between them by interpolating params a through k

@neauoire @floatvoid the gameboy processor isn’t *quite* a z80, it’s custom has a few features and instructions removed and a few other features added.

this would seem like pedantry except that it strictly means it cannot run the cp/m operating system which you might expect a z80 to be able to do.

i don’t know if other z80 os’s are compatible with it either
