Conceptual artist Diddo Velema created this 'cure for greed' syringe kit, featuring an 18 carat gold syringe and ink drawn from $10k in used currency to address the issue of greed.
Velema claims that he is inspired by human behaviour, particularly behaviours that may seem irrational or antiquated. There is a short interview here.
I discovered him via an image of a skull that he created out of cocaine. His pieces offer fascinating critique and commentary on what drives us, how we both address and mask our behaviours and how we negotiate the complexities of life, and perhaps more importantly how we manage to conquer the outer world while remaining victims of our internal make-up.
