Arty spiders of Edinburgh

Some days it seems that the streets of Edinburgh are infested with giant, arty spiders. They follow the scaffoldings builders. Then they crawl up the scaffoldings at night time and weave multicoloured nets, that stay up there until they rip and get blown away by the wind...

Or maybe they are not giant. Maybe there's a lot of really tiny ambitious spiders.

Or maybe they are student spiders. They just get drunk on colourful cocktails and go up there to weave for fun.

Wow, time to get some sleep I think...
