Added some fake transparency. But perhaps spending some chars to double up the encoding might help the most...
u/joeytwiddle

Or perhaps convert the surface into a Fourier sequence, then we can have lots of points!

Thank you u/vain for the suggestion, although I'm sure if this is exactly what you had in mind
