Jason Alleman (aka True Dimensions) built this set of microscale farm machinery. And even though I know nothing about the original subject matter, somehow I can just tell that these models are painstakingly accurate!
The only thing missing are a bunch of eviscerated cows and a flying saucer. Actually, these are so adorably playable, it just leaves me wanting more. Like, oh, I don't know... an entire microscale farm scene?!
Jason has also posted instructions to these models and more on his website. (...good man!)
