The Walking Advert The idea is simple: the design will be printed onto a T-shirt and worn everyday, for a month hence The Walking Advert Everyone is welcome to buy my pixels, which are available in 1000-pixel 'blocks' (each measuring 100x100 pixels). (If you require more space, please order the appropriate number of gigs) The pixels you buy will be displayed on the printed t-shirt. The t-shirt will not change until the refresh after a month.
