Vector Convert (Suggestion)

Most of the brushes for Adobe Photoshop can be easily converted to vector objects with the help of Illustrators, the Live Trace feature .

Photoshop Brushes are actually information about grayscale shapes, all you have to is to use them once in a blank document, export them as a jpeg, gif or png file , and then load it with Illustrator (File > Place).

The final step is to select the loaded file and go Object>Live Trace.

Note: The Live Trace Feature is avalable in Adobe Illustrator CS2 and CS3. You can also take a quick look at "Producing creative drawings with Live Trace and Live Paint"
