This is a 3D print of the original animated render, which you view on deviantArt as either an APNG or GIF image. The shape is a spherical function created using Functy with the following formula:
radius = (3*(0.5+(sin(cos(a)+(p*((3+cos((pi*0.3)-1.5))/4))*10)**2)+((6/6.6)*((2+sin(8*a))/3)**4)))*sin(p)+(4.3*(1-(sin(p)**2))),
colour (R, G, B) = (r/8, (3+sin((a)*8))/5, (3+cos(a*8))/5).
The print in full colour sandstone is quite delicate, but came out really nicely.
