I started work on a Linux distribution called Escapist based on the ideas behind Starch Linux (which is now gone) and Sta.li (which had not released any code yet).

I contributed to porting Cyanogenmod and other aftermarket firmware to the Samsung Galaxy Player 5.0. Very messy kernel and device tree source can be found at my old Github.
I also developed a stock-based custom Gingerbread firmware for that device, available at XDA.
Since then, all of my devices have been from the Nexus family, so I have not needed to

BuildSkin is a tool for generating LOTRO skins from individual panel snippets (XML fragments).
