I've played around with home made sundials for years. I think if I wanted to mark midday (or any other time) in a really clear way I'd set up two very narrow, vertical gaps so that a pencil thin line of light would appear at the required time for just 2.5 minutes every day or (if you blocked part of them) at any desired time or day.
