Tool to rank lots of different options in a survey [on hold]

Does anyone know of a tool that will show two images (or text) then ask the user to pick there choice. Then mix the order up for the next user. At the end output a ranked list of the images. Like a kinda multivariate AB test.

For example

user 1 asked to pick A or B, then pick C or D

user 2 asked to pick B or C, then pick A or D ...etc
