We don't have pictures yet but hope to have a couple of things here.
   One is a collection of interesting radioactive events from a standard homemade dry ice based cloud chamber as well as a brief section on how to build and operate your own.
   The other, if it works, will be the results of an attempt to build a small chamber needing no dry ice.  It is related to an attempt to produce a small snowflake chamber with a similar device.
   Please see me if you're curious about this.
