Pretty much everything, honestly. Pearlstone and ebonstone bricks, demonite bricks, mud with mushroom grass (glowy goodness), rainbow bricks (in limited quantities, large amounts drop framerate), slime blocks, bubblegum bricks, glass, mudstone, cactus, pumpkin, bone, living wood, leaves, and the list goes on. Backgrounds are about the same, though I recently am on a stained glass kick. I just dumped 4470 multicolored stained glass into my chlorophyte farm about an hour ago.

Variety is the spice of life. They gave us hundreds of building materials, I prefer to use them all.
