Half-spacing is using a wheel to offset a block by half a block length, like in this video:

what is half-spacing?

I think the most efficient way is to pick up a flaming ball, get a group of sheep to follow you, and set them on fire when you have a lot of sheep together. Then gather another group and do the same, until you've killed enough. That's how I did it in the demo video.

happy late birthday!

I challenge you to make an extremely stable, easy to control helicopter (or quad, any amount of rotors) with the least amount of blocks/space used!

and now for the next challenge, a ZERO button win machine XD

make a robot that turns into a crossbow sentry (imagine bastion from overwatch, but a massive futuristic crossbow instead of a minigun), a bird, and a plane! ultimate challenge, i think! ^_^

yay awsome!

it's incredible you need like 5 min. and your a pro

Very unique build, 1 button is certainly very impressive, where can you go from here, you've already mastered the low block count with the pepper mill? Maybe a no button machine? Using the automatron to beat all levels

Happy birthday Ross! Keep building these incredible machine!
Your machines are one of a kind, nothing beat the creativity of yours!

30 zones? Wow. Fit in bounding box? Holy shit. 1 button? What the fuck? I am legit trying to think out how big your brain is. I started with 50 ASTRONOMICAL UNITS (look it up)!!!!!!!!!!!!!!!

Thanks for commenting!

When I made this particular machine, I started by trying to make a version of Whirled on a String that's easier to control. Whirled on a String is basically driven by only one button, with the ther buttons operating the grabber and rocket. So I got the idea to try to make the new machine go through the whole game with only one button.

how do you even come up with the ideas?!
