Declarative knitting in the cloud!

I've talked a bit about getting this up and running, and now the website is live:
http://www.declarative-knitting-tools.com/

The idea will be that it's a place to put little knitting tools for generating different kinds of knitting patterns.  Each tool will be quite small, and probably quite niche, but the idea is to build up into a collection of curiosities.  For now it's just got one, which generates shadow knitting patterns, but over time I'll be looking to add more - ideally adding a new tool should be quite quick - particularly, the majority of the effort should go into solving the actual computational problem, rather than building the website.

For now it's hosted on an EC2 instance on AWS - I'm keen to transfer it over into a serverless arrangement, but this may be a little difficult since it has a dependency on an installed copy of OpenCV for image processing.  I don't believe this would be possible in Lambda, but it's possible there's an approach with containers and ECS which would be a good fit.
