East Bay Hackers logo; my first try

EAST_BAY_HACKERS_LOGO

 

The logo is based on the constellation Einstein’s Cross.  It was named after him because the phenomenon which creates the pattern is gravitational lensing, evidence that Einstein’s theory of gravity was correct.  The four lights are images of a quasar which from Earth’s perspective lies behind the galaxy which is in the center of the constellation.  The light is bent by the gravity of the galaxy so that from Earth we see four images of the quasar positioned around the galaxy forming the shape of a cross.
