Below is the latest selection of inspiring web finds we have unearthed this week.

At the Arab Museum of Modern Art in Doha, Qatar this week, Chinese artist Cai Guo-Qiang put on his largest “explosion event” of the last three years, utilizing microchip-controlled explosives to form incredible designs and patterns. The video we’ve embedded of the event is an impressive testament to how a volatile black powder explosion can be controlled and shaped by computer.Each set of explosions was calculated to paint a different picture. One series of explosions created black smoke clouds that looked like “drops of ink splattered across the sky.”

‘Hero’ is short film by Miguel Endara, documenting the creation of a drawing composed entirely out of 3.2 million ink dots. Simple but very effective.

An unexpected side-effect of the 2010 flooding in parts of Sindh, Pakistan, was that millions of spiders climbed up into the trees to escape the rising flood waters; because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiders webs. This photo is just one of the incredible series from the National Geographic Photo Contest 2011. See more photos here.
