Art supplies can be expensive (perhaps a reason why the starving artist image persists), but if you'd like to create for free, check this site out. The Artist's Toolkit is an interactive site where you can explore art terms, some of the history of art, watch other artists at work (an excellent feature), and create your own works of art. The site provides a strong foundation for you to build on. You can even create an image of a miner's hat with a bright light; than I would recommend using this miner's hat to explore the arts even deeper and further underground. It can lead to a whole universe of different air.
The computer has changed the face of art in a variety of ways, and this site is one of those ways; easily accesible, understandable and a lot of fun. Not recommended though for artists like Jackson Pollock, where the action and movement of the entire body come into play. Other than that, you can be dressed in your Sunday best and still paint without having to worry about getting a single drop on you thanks to the wonder of the computer.
