+# Fade
+
+So we're on to a pretty basic example that uses a uniform. In this case we're
+using a single float value as a uniform to control the opacity of the triangle.
+In this case we can use the CPU to calculate what the fade should be based on
+the time as we increment the value. And on each frame before every draw call, 
+we update the value of the uniform. The GPU will then remember that as a fixed
+value until we update it again, which happens to be on each frame.
+
+As far as opacity goes, this example doesn't exactly work. I'm not sure why the
+example shows the console under the triangle each time. So I think there could
+be some setting that I'm missing when setting up the OpenGL context.
