Charging Cradle for Extended batteries

[SeeEss]

I was *somewhere* recently, on one of the forums and saw a demo of a cradle that would charge the droid incredible. It had to be set up...you measure how far out the phone stands, mark it then add the charging thing. It is then permanent.

Unfortunately I did not bookmark where this was and now I can't find it again. Is this ringing any bells? Does anyone know where I can find this?

Feeling very stupid...
