The Dazzler has 1mb of vram available to it. Normally you send commands down spi to create images, text and so on. But you can use a Paletted bitmap to create a 1280x720 framebuffer with a palette and around 120k left for other data.

After raising a question on the gameduino forum James Bowman kindly wrote a quick demo on how to create a random image pixel by pixel. I've taken that example and have created a fractal generator which I'll share very soon. Here's a link to the arduino sketch demo from James.
