I’m using @Aaron_Liddiment 's beautiful LEDMatrix example sketch and wanted to say thanks & share. I’ll post the final video and instructable here once I finish it up.

Totally at the suggestion of Marc Miller, btw…I am having trouble tagging for some reason. 
Super cool, I did a similar project a few months back https://www.instagram.com/p/BH57puWgju4/

Oooh that looks fabulous @Amelia_T . Thanks for sharing, Amelia and Leon.
Here’s my silly video showing the final project.
Always great to see some behind the scenes and how something is created.
Very cool! You could put some fiber optic wires on the last LED of each strip for added jelly fish goodness too.
@Charity_Stolarz great tip! I haven’t played with fiber optic wire yet. This would be a great place to start. I’ll add it to the list for v.2!
That looks awesome!
