Jim Gerrish originally published many of his Wiz Kid's effects in Genii circa 1970-1988. Now he has re-imagineered many of them and brought them up-to-date with new material and presentations. Cases in point- The Lucky Duck race is now a Horse Race complete with "road apples" and funnier than ever; Star Warts is back with two new characters to add to the confusion and magic; and of course the OOPS machine is back with comments from some of the former Wiz Kids who worked with it. It's all on my site at http://www.magicnook.com
for those who are interested. Look for it under Jim Gerrish's Kid Magic.
