Stranger things Halloween Costume

I saw a really fun stranger things Halloween costume floating around Reddit and through it it would be really cool to expand upon it. It was a framed elastic that one could make it look like someone was pushing through a wall. I am semi crafty and have done a few projects with the photon but using canned code but not very good at coding where would need the help. I wanted to make the wall costume with elastic to make an illusion of coming out of the wall but also add the alphabet and add a controller (like a spark photon) where when someone texted my number I could use IFTT to light up individual lights (or letters). Seeing that this would take 26 outputs I could lower this down a bit since people probably won’t use letters like x, z, q, etc. But I am not an electrical or computer science engineer so I would need some help. Is anyone interested in building something like this with me or helping me?

26 outputs is easy. You can use shift registers, GPIO expanders, multiplexing, charlieplexing, or even addressable LEDs.

How about something like this:,searchweb201602_3_10057_10056_10065_10037_10068_10055_10067_10054_10069_301_10059_10058_10073_10017_10070_10060_10061_10052_10062_10053_10050_10051,searchweb201603_2&btsid=a5caf688-3df8-424c-8777-bb1e918922c1

Did you finish your costume?
I have a link to some code that might help you for your costume.
