1. My username is _____ because ____.
magicmarmot, because a long time back, I decided on the name Magic Marmot Studios for my studio business. That had a lot to do with synchronicity and the prevalence of marmots at the time. There was also a short lived "Mystic Marmot" phase, but Magic Marmot finally won out and became registered with the secretary of state.

2. My name is _____ because ______.
Rob, because my parents named me Robert after my father's best friend. I was also Bob and Rob-Bob at various times, but Rob is the most recent incarnation.

3. My journal is titled ____ because ____.
I had to look at what my journal is titled because I've forgotten.
I'm Pretty When I Lie
Taken from the VAST song. I have a lot of issues with self-image and honesty with myself and others, so it resonates.
Subtitled If I wanted your opinion, I'd eat your BRAAAAAAINS! because of my love of zombies.

4. My friends page is called ____ because ____.
Sleeps well with others. Inside joke, snarfed from loba that was a cascade from a "plays well with self" T-shirt. It's probably time to change it to something else, but I really don't care about the name of my friends page, more about the content.

5. My default userpic is ____ because ____.
Currently, it's this:
It's taken from last year's CONvergence facade, which was my brainchild, and it covers a lot of niches, from my love of the spooky to creative outlets, to nifty solutions to difficult proposals, to completion of projects undertaken, to a particular mood. It's motivational whenever I see it.
BTW, the red stuff on the skull is silicone. It looks really gross and liquidy, but in reality it was quite solid and reasonably durable. I discovered how to make a kind of paint from it and dye it different colors, which amuses me to no end.

The weird root-shaped things are made from cans of spray foam, then painted and gooped with the silicone. They were supposed to look like evil root things, and I think they worked quite well for that.
