[Rob Stewart] put in a lot of time and built this lighted display at great expense. It displays four letter words using a word association algorithm to pick the next term to show. What interests us is the motorized display. It is made up of fluorescent tubes but they’re not fixed in place. Each can be rotated, as well as moved along a linear path to form any letter in the alphabet. Check out [Rob's] build logs for the details on how he pulled it all together.
