My username is Spartacus because, being a radical socialist and a Marxist, I see Spartacus (the historical character) as “A great general, noble character, real representative of the ancient proletariat,” as Marx called him. The 01 in my nickname comes from the fact that I was born in 2001.
I have the habit of changing my Avatar very often. But whatever, if I had to explain the avatar I have right now, I put it simply because I like astronomy, I like space, and I like cool wallpapers that have astronomy and space as a theme.
