HFSG and either his friends or membership clones have posted at several other audio forums on the web. Always glowing reports about the clocks, pebbles, foil, cream, etc. Some of the posts report some blind testing with friends and positive results. At least one 'person' reported positive results by introducing a $10 or $15 clock they bought from an everyday store.

I see three possibilities.

1) The products developed by PWB, based on whatever ideas he has about the more-than-physical universe, cause genuine, verifiable results. If this is true, then there are effects in other than just audio/video perception.

2) One or more persons are creatively posting for their own entertainment, to laugh at our reactions, or other agenda.

3) The perception of various people, to varying degrees, is affected merely by the idea that something has changed, whether they have a good idea of what is going on or not.
