Cool! I made half a sphere with 0.5+sqrt(0.2-((x-0.5)^2+(y-0.5)^2)). If there was a way to do a mirroring on the xy plane (as in a +/- z value) it could be a f

  that's so cool! btw, you can link to your equation here http://vicapow.github.io/equation-plot-webgl/index.html#0.5%2Bsqrt(0.2-((x-0.5)%5E2%2B(y-0.5)%5E2)) edit: but HN seems to be messing up the urls :(

  I managed to modify yours to make a full sphere with a bad hack: http://vicapow.github.io/equation-plot-webgl/index.html#0.5%2Bsqrt(0.2-((x-0.5)%5E2%2B(y-0.5)%5E2))%20*%20(round(random())%20*%202%20-%201)%20 http://vicapow.github.io/equation-plot-webgl/index.html#0.5%... There's probably a better way to choose which points go above and below than random(), but it works. Edit: Got it to work non-randomly. Adjacent dots alternate above and below: http://vicapow.github.io/equation-plot-webgl/index.html#0.5%2Bsqrt(0.2-((x-0.5)%5E2%2B(y-0.5)%5E2))%20*%20((0%20%3D%3D%20((x%20*%2040)%20%25%202))*%202%20-%201)%20%20*%20((0%20%3D%3D%20((y%20*%2040)%20%25%202))*%202%20-%201)%20%20 http://vicapow.github.io/equation-plot-webgl/index.html#0.5%...

    It seems the result is a complex number. Fiddled around with it a bit until I got lucky and got the plane to disappear. http://vicapow.github.io/equation-plot-webgl/index.html#0.48-re((sqrt(0.15-((x-0.5)%5E2%2B(y-0.5)%5E2))*i*100%20%2B%20(sqrt(0.15-((x-0.5)%5E2%2B(y-0.5)%5E2))%20*%20(round(random())%20*%202%20-%201)))) http://vicapow.github.io/equation-plot-webgl/index.html#0.48...)
