Visual Effects

Last night while lucid I found myself looking at this flag/banner thing, and telling it to change colors, telling it to be red, then green, then yellow, and so on, and each time it would change as though someone had put it in Photoshop and adjusted the hue. This was pretty cool, and then as I started walking away I did it to the entire field of grass, making it purple, and then I just gestured around and said, "EVERYTHING GO PRISMATIC," and things got really awesome. Every single surface and object began spastically running through different colors, the grass, the sky, the clouds, everything was going nuts, and it was insanely beautiful and cool.

What other sorts of visual effects like this can be achieved in dreams, I wonder? Was this effect a change of the actual dream world, or a change of the lens through which I view it? Could I, say, 'will' distortion bubbles into my visual field that would distort or lens whatever was behind it as I turned my head, or could I only will the bubble into one location? Is it possible to induce visual pattern noise like that experienced on Acid or Mushrooms?

EDIT: Could I, say, have an entire dream viewed through a Photoshop sketch filter?

If your command about everything going prismatic worked, I don't see while photoshop filter wouldn't. If you familiar with it and you know what it does, I'm sure it will work.
