|¡Continuous Line Art
One day,I found my doodle I drew during calling was really nice.So I started continuous line arts.
A Penrose tiling is a nonperiodic tiling generated by an aperiodic set of prototiles named after Roger Penrose, who investigated these sets in the 1970s. I am impressed by the fact that only two piece of tiles generate infinitely different pattern. I suppose that it like to the rule of the world.Connections between symple elements could generate the complex world.
|¡Islamic tile patterns
Do you know "girih"? It is intricate patterns covered Islamic mosques in Middle Ages. It was assumed that the patterns were created using a compass and a straightedge, but now it seems that ancient Muslims may have stumbled on some advanced geometry, not discovered in the Western world until 500 years later.

It is often said that the RPG world is not sphere but doughnut shape. They disappear at the top of the world and appear from the bottom of the world. They disappear at the western edge and appear from the eastern edge.

Boustrophedon is an ancient way of writing manuscripts and other inscriptions. Rather than going from left to right as in modern English, or right to left as in Hebrew and Arabic, alternate lines must be read in opposite directions.

"A few years ago,a lot of mosquitoes swarmed over in Roma. The investigation revealed they breed in sewage that have been used as long as 2000 years. Roman found that they have never cleaned for 2000 years."
|¡How to depict four dimension world
I have been learning "four dimension world" since I came across a book "The Fourth Dimension A Guided Tour of the High Universes" by Rudy Rucker.I did not know which was the fourth dimension,time or space??,but now I perceive they are identical elements.
|¡The view from the underground
I heard about the unique maps reversed left-right.Some ethnic groups in ancient China drew the maps viewed the underground. But you know,the constellation maps are drawn from the underground not an overhead view.
