A linear instruction stream maps cleanly onto a grid. A similar scheme is the basis for [stack machines](https://en.wikipedia.org/wiki/Stack_machine), which is probably where I first encountered the idea (many of the first Lisp compilers targeted virtual or "bytecoded" stack machines. The JVM is the world's most successful stack machine). -But it wasn't until I encountered Christian Lawson-Perfect’s excellent [Nice Calculator](https://somethingorotherwhatever.com/items/clp-s-nice-calculator/) web app that I started to use an RPN calculator day to day. It renders expressions as editable bubbles in a tree, which is a beautiful UI idea. I wanted that same editability, but with a layout that uses screen space better on a phone, any with a way to refer symbolically to previous values and results. +But it wasn't until I encountered Christian Lawson-Perfect’s excellent [Nice Calculator](https://somethingorotherwhatever.com/items/clp-s-nice-calculator/) web app that I started to use an RPN calculator day to day.
