Like Creative Computing, I remember the pleasure I got from Algorithm Magazine, which included pseudocode for fractals, neural nets, cellular automata, and all those things that attracted me to computers. Algorithm Magazine was put out by noted computer scientist and author Alexander Dewdney (http://www.csd.uwo.ca/faculty/akd/akd.html).

I would gladly scan the few hardcopies I still have (not a complete set though) if someone else would host them.
