“Draw 10 pictures of a bottle (any bottle shape is fine). In each bottle, draw one object. The bottles, when placed in sequence, should convey the passing of time. For example: an easy solution would be 10 apples, from ripe to rotten. Try to take this further: How much time will pass from your first bottle to your last? What will you show in the bottles? What impact can you convey?” How to Design brings us today’s prompt again. They are too awesome to ignore! Thanks to @ryanseslow for pointing us to this website.
