How To: Make An Endless Folding Picture Cube (Using A Dragonball Z Example)

This is a video of Youtuber Elde Art demonstrating how to make an endless folding picture cube, using one of his own Dragonball Z cubes as an example. I won’t lie, the tutorial looks more complicated than my current skill set is capable of tackling. *shrug* I’m a simple man. Besides, who needs to know how to make endless folding picture cubes when you can make a paper fortune teller? “This is just a scrap of paper that reads ‘Now you gonna die!'” LOL *brandishing knife* at least it’s accurate.

Keep going for the video.
