comment '(Pseudo)-random functions' by seeding of PRNGs?
Just so I understand your question correctly: you have an integer lattice/grid, and you want to associate with each point in the grid a pseudorandom number? Why would you have to cycle the PRNG for each point in the grid? That sounds like an excellent way to easily exhaust the period of your PRNG if your grid is fine enough.

comment Mandelbrot-like sets for functions other than $f(z)=z^2+c$?
Since you mention how Newton's method gives rise to fractals, I remember that Kalantari made a study of how different iteration functions (Halley, Chebyshev) that are higher-order analogs of Newton's method can also give rise to fractals. polynomiography.com seems to be the outgrowth of this particular work.

comment Closed form of a partial sum of the power series of exp(x)
His second sentence says "I am already aware of expressing it in terms of the gamma function," though I am no longer sure what sort of answer(s) is he expecting since an incomplete gamma is not satisfactory for him as a closed form...

Sounds good, I decided not to be anonymous anymore after spending an hour browsing here. :)
