I love random anything generators really. Just saw a link to a random knitting chart generator (very customizable, so you can indicate whether you want lace, etc.)
and i woved to knit the first chart it generates for me.
It looks pretty nice to me.
There is also a genrator for cable patterns at http://babyzcostumeshop.comyr.com/tools/knitting/knit-cables-generator.htm
and my first cable pattern is also pretty.
