well i guess it's not "true vector" since it would become pixelated if you resized it. however, aside from the text, it is made up of all lines and basic geometric shapes which is what vector is defined as.

edit: sry bfg didn't see your question the first time around, but yeah i did all the vectors myself. i especially like the bullseye lookin thing in the lower right. that started out as a series of black and white concentric circles which i then used "distort" to change the perspective.
