Listed in this timeline are but a few examples of the various versions of the corrupted cone, starting in 1977. If you have an example that you think should be included in this timeline, please contact me at betrusak@potsdam.edu
Note: Do you have an example of the corrupted cone that you still have posted somewhere in your web space? If so, my advice to you is to take it down. If you think that it is unique in some way, or otherwise should be preserved, please send it on to me, with as much information as you have about it, and I will post it here.
