We've already seen IKAROS' view of its deployed sails from cameras attached to the spacecraft, but, in a brilliant idea, the Japanese built IKAROS with two deployable cameras that could view the thing from a distance.

Several pictures from the sail deployment monitoring cameras showed up on the IKAROS blog overnight.
