Pstricks is too cool! I started to paint a colorful picture with SmartDraw, exporting PDFs nearly 2m, very bad! Use PSTRICK in the morning, and finally get a PDF only 90K! Wonderful! Also, I don't know how to save the results of Pstricks to a separate file, just like Metapost. So I use a stupid approach, one file only generates a picture, then cut it in the PDF, still good!
