Recent is relative right now, but here's a few things I've done in the past that I thought were worth bringing to the new site.
A simple but flexible in-browser corkboard.
This generates random maps/caves based on a cellular automata algorithm.
JRPG-styled chat windows for the masses! Kinda neat for RP things and whatnot.
So, a while ago, while working on a project that's a bit too early on to post here, I was getting frustrated at not being able to keep track of various snippets, classes, etc, in JavaScript.
Enter the corkboard.
Basically, you can make little notes and arrange them however you
like. It's a bit finicky in places right now, and it only does text, but
it's a nice tool for keeping track of lots of little things.
