I guess I don’t have a complete blog entry to write on any one thing.. but there are several unrelated things that I feel like writing down. I recently joined Twitter, but I must suck at using it because none of these things ended up there. Life Tragic. Introspective. Complicated.

As far as I can tell, this all started when I was at Fry’s drooling over the Lego Mindstorms in the toy aisle. The abundance of toy helicopters caught my eye. I didn’t buy one... Read More
