Can't reach the cobweb on the ceiling with your regular vacuum cleaner attachment? Try using a long, empty wrapping paper tube to extend the reach. You can even crush the end of the paper tube to create a crevice tool. Use duct tape to make the connection airtight.
Need to use this to organize all those random cords that get tangled up. Maybe jazz it up by decorating the tube with fun paper or painting it? Maybe label the tubes or color coordinate for easy organization.?
