Things I've made
Pages
Occasionally I create a single page to try something new and be creative. Sometimes they're even useful.
Here's a visualisation for Twitter. Give it something to search for and it will show those tweets.
Barnsley's Fern on a HTML5 canvas. It's 180,000 green dots drawn using a simple formula, and it ends up looking quite nice.
A tool to calculate the probability of a hash collision. It was meant to be a simple bit of code with lots of CSS to make it pretty, but that was before I started looking at JavaScript big number libraries…
Websites
davidjohnstone.net
This is the website that you're looking at now. As you might be able to tell, this is where I keep a blog, make the occasional fancy web page, and might someday do a bit more.
Find a Presbyterian Church
A directory of Presbyterian churches in Australia. Like most things I make, I can think of plenty of ways to improve this.
MarkItDown
This is a note taking website that I created because I wanted to use it. I think it's really useful.
Cycling Analytics
This really consists of just one page, but it's a good page. There's lots of graphs and numbers, and it's going to become a lot more than a single page soon.
