You can get imshow to be fast. If you save the object returned fron the call to imshow, there is a method called set_data() (I believe), which you can pass values to after the initial call. I have gotten very good framerates on my EeePC doing that. Most of the computation in imshow is with respect to the creation of the object, not the display.
