The simplest solution would be to use Gravatar, Unicornify, or another free online identicon solution.

Otherwise:

• Hash the e-mail address, for example by xor-ing all letters together.
• Encode this to some small set of numbers, for example 8 numbers between 0 and 15.
• Use each number in some way in the image. For example, one or two number for color, a number for size or shape of some part of the image, etc.
