All graphics with pyglet are drawn using OpenGL. One way to draw rectangles is: from pyglet.gl import * glColor3f(1, 0, 0) # red glRectf(x, y, x+w, y+h) A more efficient way to draw the entire array is to copy it into a texture. Use the pyglet.image.ImageData to create and update the data in a texture, which is then drawn using the blit() method. If your numpy array is not in a format that ImageData can use, you can use the glTexSubImage2D call directly, with a little more effort. If you've never used OpenGL before this task is going to give you a steep learning curve -- you may want to skim some of the many tutorials around on the net first. You could also take a look at http://groups.google.com/group/pyglet-users/web/2d-drawing-primitives-module, which provides some simple drawing primitives without needing to know OpenGL.
