During the past week or so, I've been laying more groundwork for my web application sandbox. Although it's still very spartan in style and spare in content, the sandbox landing pages (http://bradleypmartinsandbox.com) are now quite a bit cleaner. You can check out a screengrab of one of the pages below, or head to the site yourself to take it in! I've also built in functionality for the sandbox page to link to other servers hosting specific applications. Right now there's only one bare-bones app being served (linked in the greet button of Figure 1), but I'm hoping to expand this selection soon (and with much more substantial applications).
Figure 1. Here's a shot of the cleaned-up 'secret' page from my last post (now in the 'appselection' route). It now serves as a link to other web apps I've built, but you still get a kitty picture!
I'll try and involve many of these JS tools as my sandbox/portfolio applications become more substantial.

Figure 3. This clone of a noteworthy, animated presentation by Hans Rosling of gapminder.org shows relationships between GDP, life expectancy, and total population (circle area) for different countries (individual circles) on different continents from the year 1800 up to the present. D3 and its community make a ton of cool data-driven functionality possible, and I'm looking forward to using that in upcoming projects.
