Off the top of my head:
sand; real dirt; sawdust; aquarium gravel; peat moss (one of my favorites); those brown things that fall from trees in the spring; dried crushed leaves; bits of sponge; ground foam; sifted "tube sand"; coffee grounds; bits of bark; artificial coal; chalk dust; shredded lichen; tiny twigs...
...and, my absolute favorite: The random crap that I scraped up from my last layout.
Now that`s a good list, thanks..
