Came up with an idea! The new Rayovac 1AA headlamp has a really cool rotating diffuser on it. After taking the diffuser off the Rayovac, I placed it over the lens of the EOS and it works fantastic. I just need to figure out a way to secure it to the EOS so it can be rotated back and forth over the optic. This may involve drilling or glueing a small post next to the optic for the diffuser to rotate on. I'm gonna work on this mod when I get some time this week and will post my results.
