  Interpolating between textures using clock?

I have an object that simulates a generic computer screen using the `cells`
texture to generate a grid of random-colored pixelated blocks.  I'd like to make
an animation of this where the "screen pixels" gradually change in color based
on the `clock` variable. Is there a simple way to do this?

My current idea is to somehow interpolate between two `cells` textures (by
displacing them relative to each other by some random integral offset) and doing
the equivalent of pigment1*clock + pigment2*(1-clock). So basically interpolate
between two random cells patterns according to the value of clock (or some other
such derived variable). But I can't figure out how to express this in SDL?  Can
anyone help?
