I saw an intersting metal scuplure while on a trip in back in 2004. I drew a quick sketch of the scuplpture in my notebook and forgot about it. 11 years later that notebook barely survived an unfortunate fire. The sketch was still intact and I decided to create more illustrations

I published the set of 10 icons on The Noun Project where they have been downloaded a total of 7000 times. The set was also given a mention on The Noun Project twitter account.
