More Quaternion Julia Fractals are available at Dave's Graphics Page. Also check out Paul Bourke's Quaternion Julia Fractals site. It's one of the best sources of information on Quaternions that I've found.

I want to thank everybody who donated to this site to help get me offset the massive bandwidth costs caused by the recent Google julia fractals image search extravaganza. The donations ($280 in total) covered more than the cost of the bandwidth usage for this month (projected to be about $200 as long as I don't get hit hard again). The extra donations received will be used to pay for the next 6 months of hosting and an account upgrade which will allow me to post much more material in the future. Sincerely, Dave.
