You can take 8192 bytes of information (1024 x 32 bit floats) and reduce that to 128 bytes (1024 bits, a 64x reduction in size!) and still get results that are about 95% as good.
I find that cool and surprising.
1024 bits for a hash is pretty roomy. The embedding "just" has to be well-distributed across enough of the dimensions.
I'm with you, it's very satisfying to see a simple technique work well. It's impressive
