can you identify this bug or suggest what it might be.  

It was flat and brown. It looked like a medium to dark brown dime with close tubular appendages all around it. Like fringe around a dime to make it a little larger than a quarter.  I saw it in the corner of door molding and am not sure if I saw the whole thing. So, perhaps it was only half a dime with fringe on it. It moved very quicky when nudged with a toe. It looked nothing like a sow bug or millipede.
