This was the result of a particularly bad bout of insomnia from me. It was getting hard to tell if the lines and circles I was drawing were straight without guides, and the guides I had on hand were too consistent.
So I wrote this - it is very much hacked together quickly - a tool to practice drawing some arbitrary lines and circles. Maybe ovals at some point, if I get to it. Probably won't for a bit.

Local development: npm run-script start
Production build: npm run-script build-prod
(notice: you'll have to update dependencies in index.html to point to React cdn)
This project is a piece of shit, but it's very useful to me at least. Maybe it is to you. I'll gladly accept pull requests.
