I read an inspiring and knowledgeable excerpt from my friend's book today.
A nice refresher to keep up motivation on creativity as well as good historical references to keep the mind juices flowing.
Art Gate is conceived by Frank Navarro, who is a contemporary art philosopher. He has very exciting and accessible programs that spark interest and support the concepts in contemporary art to create a deeper understanding.
To clear your mind, stare at the Yves Klein blue for a while....
Consider signing up for an Art Gate workshop/class.
