@jamesthomson I will call it “Big Calc”

Feature list is basically:

- simple arithmetic calculator + - x ÷, and then
- ability to display numberlines beyond exponents
- decision tree for 0,1,2 and “other” (zero, infinity)
- probably include a size-comparison tool
- (this may require a dual display?)
- maybe include ^ exponent operand if it’s easy

But first — and most fun — is I have to craft a simple-ish way to display several forms of “big” numbers (tetration, etc). I am deciding whether to aim for ASCII 1-dimensional, Unicode 1-dimensional, or LaTeX etc levels. The reductive approach appeals to my geekery; the fancy symbols will appeal to users who have heard of Graham’s Number and TREE(3).

I’ll just call them downloaders. This is a toy I’m making. Maybe an educational toy, but a toy nonetheless.

I discovered most of what I’m using by forcing myself to craft a programming challenge question about tetration, many years ago. That’s when I discovered most (if not all) of the operations go into “orbit” if you don’t use 0, 1 or 2.
