Sometimes, I (try to) do too many things ... all at once :) I'm not the only one who has little time. I know.
Here is a fraction of things I do apart from working, as time allows of course:

1. write notes and reminders that I consider useful for others in my blog.
2. develop(ed) and maintain the Non-Photorealistic Rendering Library (NPCGLib).
3. pre-built binaries for a number of libraries for both Windows 32 and 64-bit.
