Tie 'Em Up
If you have a power strip (or four) of cables hanging out in the same place, there are many solutions for grouping the cables into one smooth set. Velcro cable ties are easy to remove if you have to pull the plug frequently, or pick up a set of zip ties. If you want to save a little dough and can deal with function over fashion, some loops of good old-fashioned duct tape will do the deed just as well. Just be sure not to wrap the cables too tightly together -- no pinching allowed.
