Lid for a 10gal tank?

[jipps]

Anyone know what I can use to create some sort of light-permeable lid for my 10gal tank? I know glass tops are out because it restricts the gas exchange and heat release.

I went to home depot and asked for plastic eggcrate that looks like a grid and they looked at me like i had 8 heads. anyone have suggestions? I don't want my clowns jumping out because when i had my aquapod they both jumped into the back compartment...i don't know how, but they did.
