Andrew Jenner: Nice blog post!
I used the table of squares trick for a Julia fractal morph back on my 486 25 MHz. The speedup was very significant on the 486 as well (and needed to make the effect run smoothly), even though I think I used 2ab = (a + b)^2 - a^2 - b^2 because I hadn't figured out that 4ab = (a + b)^2 - (a - b)^2.
