Scratch

Anything is possible if you set your mind to it 

It is possible if you make a bit of 3d engine. It doesn't have to be full 3d, considering that, despite the above quote, it's practically impossible, but just little squares floating around as you drive through a field is certainly possible

Cool. Yeah, I know scratch isn't a 3-D programming thing. I was just worried about the programming. Like how to make more cubes appear without making thousands of cubes.

You wouldn't need thousands. Just make the vanishing point really close
