A quick search of the block library yielded 2 NYB blocks and 4 kaleidoscope blocks. And yes, you can easily alter, modify, and design your own.
There are over 1000 blocks and block variations built into EQ7. There are a few add-ons available to purchase, but EQ was designed very well to stand on its own.
