A more tile-like appearance can be gotten from scored block, which reduces the apparent scale of the standard 16x8 block face. It makes a big difference in appearance and adds very little in cost. The single score block is pretty standard. Double and triple scores are possible with a special order. This gives you a choice of 8x8, 5.33x8, and 4x8.
It’s also possible to use various sizes of block to get a more un-block-like appearance, something more like stonework.
One caveat, if the wall is load-bearing or quite tall it may need grouted reinforcing in the cells of the block. The cells need to line up to allow the placement of the reinforcing. Many of these bond patterns do not have aligned cells that will accommodate the reinforcing.
Below are 50 patterns that you can create with standard sized block. As you can see, there are many ways to add interest to an otherwise utilitarian material. These graphics come from the Reading Rock Block Catalog, which is a very handy reference.
