Create custom marker in Google Maps for Flex

I have to create a marker with 3 triangles at 120 degrees with each other. The fill colour of the three triangles will be different (to be decided depending up开发者_开发百科on the value of some other variable).

Google Maps can accept DisplayObjects as markers. How do I go about creating one manually?
