Probably not too surprising but you can approximate this whole process pretty nicely with a low-pass filter.

Pic related is the 300th 3-peano overlaid onto the first 40 coefficients of the DST of its (adjusted to make it periodic) data on the left, and on the right is the 300th 7-arrow overlaid onto the first 80 DST coefficients.

Here's a PDF with the all of the computations
