Origami tessellation

Something most intringing about origami tessellation is that... It's nothing straightforward... you don't simply push it hard down to get the shape form...

It takes a lot of messiness till the pattern unfolds....

Some genius like this guy came up with a diagram so complicated that I could hardly follow....

Finally got it done...

Tried to do it the second round... got the diagram printed on the wrong side of the paper... so I had to tried to fold it in inversed fasion... and... got it out... 8-O
