It was a simple attempt to explain to kids what a roof is, what type of windows could be and how houses of different cultures look like with the help of improvised stuff and a tablet.

I’ve just used grains, seeds and other garden stuff that I collected when I was a child.

With some handdrawn sketches it turned out some funny pictures that they liked so much that I began to draw others. 

So this is how grains have sprouted in architecture:-)
