this speeded-up mri of a pineapple was imaged at boston university medical school and a few of the images were published on mashable.com. i particularly like the tomato.gif. mashable has a link to another website that had more images~very rich! but i had too many tabs/windows open and i crashed the browser … maybe another time
i first saw this .gif on google+ where someone commented that this is exactly what .gifs were invented for… i’m glad the comment was not regarding the utility of mris!
