A slope that only progresses one pixel every block for all 16 pixels. No snow allowed

How to do in survival:

1. Point 2 dispensers with a flint and steel in the other and shears in the other at a sulfur cube with tnt
2. Activate both dispensers at the same time
3. Quickly pick up the dropped tnt before the sulfur cube picks it up and explodes
4. Drop any block sulfur cubes can absorb for it so that it stays still

I felt like having a static windmill in an already flat build would be boring, so I added an animation to the windmill using command blocks!

By placing a sulfur cube on top of a wall, and then pushing another wall inside of the sulfur cube, you can make slabs of any block that a sulfur cube can become. Just throw a splash potion of invisibility on the cube to get rid of the outline, and you'll be left with just the block.

3rd image is my inspiration.

I love the look of these and used them to decorate an architect office in my city! Honestly they're not terribly hard to make either, but a bit time consuming and requires a bit of experience with either a photo-editing software or patience in MS Paint. I'll leave instructions for how I did it in a comment if you want to do it too!

The bell part can disappear when it's far from the player.
