INFO
A collection of widgets and little programs I've compiled (and sometimes use) over the years. Some of it is obviously just for fun, and some of it can be used (and has been used) in various projects. Quite a few of them are Proofs of Concept. This is the stuff I get up to in my free time.

Please note that not all of them conform to accepted best practices. In fact, many of them don't. The key thing here is the idea behind, not so much the implementation.

I have made a point of indicating the technologies used (predominantly HTML, CSS and JavaScript) and the browsers I have tested the code on. If the code does not run on the browser indicated, check out the GitHub source; likely there is a branch within the repository that will work as advertised.
