Joke thread?

What interesting propertitties do you notice about the following expression?

exp(-((x-4)^2+(y-4)^2)^2/1000) + exp(-((x+4)^2+(y+4)^2)^2/1000) + 0.1exp(-((x+4)^2+(y+4)^2)^2)+0.1exp(-((x-4)^2+(y-4)^2)^2)

Damn, I'd take some partial derivatives just to lie tangent to those curves.

Holy shit, I meant to copy that and wolfram it but I accidentally googled it and got a 3D rotating plot of higher quality than wolfram.

What have I been doing with my life these years?

Also, nice plot.

I understand if you don't get it, it's pretty meta, plus it's an inside joke.

I'm new to /sci/, so what's the inside joke here?

There isn't one, it's an "inside joke" because it's self-referential.
