I’m very new to the world of adafruit but I’ve taken look at some projects and I want to try and get some better direction on this cosplay project I want to complete.
I’m making a helmet with an irregular matrix in a zigzag configuration attached similar to the Bluetooth Guggenhat project here on the site. I want to know how can I use the matrix to receive gifs to play and jpgs to display in real time if possible. If not in real time can I store the images and cycle through with my iPhone? Can this all be done with with Bluefruit Connect for iOS

BLE won't be fast enough for real-time video. In practice, its maximum data rate is a few kilobytes per second.
For that kind of thing, it will be much easier to use a full-scale computer like the RasPi Zero-W:
https://www.adafruit.com/product/3400
It has enough memory and CPU speed to process real-time video and decode formats like animated GIF and JPEG. It also has built-in Wifi which you can use to create a control interface.

Wanted to give an update. I found out the Avengers Campus in Anaheim is now selling LED goggles similar to what I want to do with around 7 different animations cycled with button presses. If I anyone can point me to how to do this from scratch, that would be great. Here is a video for reference: https://youtu.be/gFS-u5wJkko

Re: Beginner -Bluetooth
When you say, “button press”, do you mean a physical button on the glasses, or buttons in a BLE interface running on a phone?
Both options are possible, and the code that does the LED animation will be pretty much the same in both cases. The difference would be in how the microcontroller receives and interprets the control signals.
We have lots of tutorials in the Learning System that cover LED animation:
https://learn.adafruit.com/category/led-pixels
several of which are for glasses.
Don’t limit yourself to only those tutorials though. The basic ideas of LED animation work equally well for any form factor. Look at several projects and try to find the things they have in common, because those are the basic vocabulary for what you want to do.

Re: Beginner -Bluetooth
Thank you, this definitely points me in the right direction. I would be trying to use buttons in a BLE app

Re: Beginner -Bluetooth
Okay, the BLE NeoPixel Goggles project wil be a good reference:

Keep looking at others though, until the hardware and programming techniques start to look familiar. All technology is basically a remix of pieces other people have made before, so break projects down mentally as you look through them. You'll find useful bits in projects that have noobvious connection to the one you're doing.
