I laid out a microfiber towel on my build table when I'm doing things with screws; the towel tends to catch the screws so they don't roll all over the place. It's not perfect, but it definitely helps stop a screw from bouncing and rolling off the table, into the carpet, never to be seen again unless I step on it barefoot just right.
I'm going to steal my dad's magnifying lamp the next time I'm down visiting him, though; he never uses it anymore, and since I do miniatures and rock painting as well, it helps me to see when I need to get some nice detail in certain areas.
