The PhotoChaining blog is a continuous project where people randomly leave memory cards in public places to be picked up and used by others, who then do likewise. First, take funny/original/humoristic/creative photos with your own camera using a cheap memory card. Then write a note in which you explain the PhotoChaining concept to the “finder”. You also provide a name to the memory card (research on PhotoChaining to ensure that the designated memory card name has not already been allocated). Put the memory card and the note in an envelope. Hopefully the “finder” will pay it forward and you will be able to track images and the journey of your card online.
