##What is Opal?
Opal is a vector drawing library with an API similar to Quartz 2D http://www.cocoadev.com/index.pl?CoreGraphics. Opal is built on top of Cairo http://www.cairographics.org.
Opal is also a gemstone consisting of amorphous hydrated silicon dioxide (SiO2 · nH2O) which is sometimes included in the quartz group of minerals.
