Ahh this brings back memory of Win 95 and 2000 SE.
I thought about bringing this idea up to my teammate about this very exact thing, but went down the different direction.
What throws me off was the calculator, trying to get the negative sign was a bit difficult and hard to do. Normally alt +F4 or Ctrl + Shift + Escape would usually solve this problem.
Love it! Got out of control and got 179 points as my final score before BSOD.
