This was an intriguing request. It took a while to collect them all, but here they are:

I arranged them into five groups. Clockwise from the top left: family room, exercise room, office/sewing room, master bedroom, guest room.

Individual remotes from each group are as follows:
Family Room - universal remote, VCR, television, HD TiVo, receiver, DVD player, light control
Exercise Room - TiVo, television, DVD/VCR combo unit
Guest Room - stereo, television, DVD player
Master Bedroom - DVD player, television, portable DVD player
Office/Sewing Room - heat pump, fan, PC video card, stereo, DVD player, television

We have way too many remotes and electronics.
