```Hello, I'm a beginner to python; I wanted to make a fun little game, so I
started with something simple: Rock, Paper, Scissors.

The program I made satisfies me, but I want to add graphics.  I installed
pygame, and have some svg's that I want to render into graphics.  I
installed cairo, but then realized that it is only used to draw svg's and
other graphics into files, not render them on the screen.  Any ideas how to
start turning this into a graphical game?  Feel free to add any other
suggestions as well :D:D:D! Thanks.

Here is the source code:
