Anybody do anything interesting with their case's leftover foam?

Has anyone done anything interesting/useful with the leftover foam from their Mavic cases? It's nice, dense foam that feels like it could be useful. But right now it's just garbage taking up space in my closet. Just looking for ideas.
Thanks

My employer regularly recycles metric buttloads of foam of all sorts. I've been trying to think of a use for it for years. Other than packing material, I've come up with nothing.
