A couple of projects I'm currently working on or have worked on in the past:

pSHorthand - a shorthand system based on Teeline and Ithkuil Status: First version, will publish full specification soon.
Sparksara - a web application to generate ideas, using various methods. Ruby, HTML5, Processing. Status: Haven't started yet. :)
Left-hand Dvorak MirrorBoard layout. - A Dvorak version of Randall Munroe's Mirrorboard layout. Status: Fully working implementation.
And quite a lot of other things. I need to redesign and update this page, I think.
