Call for Digital Spray Paint
Velvet-Strike is a collection of spray paints to use as graffiti on
the walls, ceiling, and floor of the popular network shooter
terrorism game "Counter-Strike". Velvet-Strike was conceptualized
during the beginning of Bush's "War on Terrorism." We invite others
to submit their own "spray-paints" relating to this theme.
