Modular Origami Part 2

I wanted to have my basics right, so I attended a 2 hour workshop at Japan foundation New Delhi.It was very basic one, valley folds, mountain folds, water bomb, square folds, triangle fold etc. 2 small kids and few super rich housewives were attending the class. I learned few things but I was itching to do something which is difficult to assemble and form. So , here started my tryst with modular origami.
I started with tricorne, jackson cube, icosahedral .
