Deanne, I love the idea of the vibrating furniture, but we don't need it done by a computer. We have a kid down the block with a stereo system in his car that shakes our concrete house as he drives by.. a house that withstood hurricane Andrew, with under $1000 of damage, and his bass shakes it, imagine! Tim Allen used to say he dusted by duct taping the nic naks to the shelves and using a snow blower........I think that's extreme! Glad your dad still enjoys computing. I used to be a tight programmer, i'd write one line of BASIC and drink a Martini, 3 lines and I'd be out of it............ After awhile I got much more adept...at drinking!:-) Ken
