I’ve decided to move ahead with my halloween costume resembling Eve from Pixar’s Wall-E. I’m particularly interested in Eve’s vocabulary of moods as demonstrated through her different eye-states. This is an important part of her character building in Wall-E as we see her character go from a mindless mission driven robot to the considerate and caring character that audiences love.
To tackle these different mood-states I’ve decided to use an LED matrix for each of Eve’s eyes and glue them to the inside of a full-face sunglass visor.
Below are a few examples of different mood states I could express via the LED matrix. It’s particularly useful in this case that I may be able to use different colors through the RGB matrix to express enhanced states like anger.

I think I will mostly have a loop of alert with a ‘blinking’ animation loop to give the eyes effect. I will include a button on the visor or battery pack to toggle between mood states.

Hi Tristan,
I’m Yennie 🌻
I really love your idea of using an LED matrix with a blinking animation loop to express facial emotions!
Looking forward to seeing your Halloween costume!
Thanks 🌻
The idea is really cute, but I’m not sure how it will actually look when you put it on, especially the white headcover part. I’m curious what kind of outfit you’ll wear to go with it.
Just like Jay, I’m really curious about what outfit you’ll wear to match it — I’m so looking forward to your showcase!
