Use an Adafruit LED Matrix Portal + 32x32 LED display to create a sign showing an animation of the Swift language logo.
Same code also works on a 64x32 LED display (that's the one I use for Baby Yoda). All you need to do is modify the matrix_width = 32 line so that it reads matrix_width = 64
Then also be sure to use properly sized .bmps
An example of the project in action can be see in this Tweet: https://twitter.com/gallaugher/status/1317206066770399232?s=20
And here's one using the 64 x 32 with Baby Yoda https://twitter.com/gallaugher/status/1321834321024528385
Hardware used: Adafruit Matrix Portal: https://www.adafruit.com/product/4745 32 x 32 RGB LED Matrix Panel (I used a 5mm, but you can use any of the other mm sizes): https://www.adafruit.com/product/2026
And the Baby Yoda uses 64 x 32 (I used the 4mm pitch, but any pitch size should work): https://www.adafruit.com/product/2278
You'll also need a USB-C data (not just power/charging) cable to connect your Matrix Portal to your Mac or PC for programming, and to a standard USB power supply - like the small one that you might use to charge most mobile phones - to independently run this.
Also: In the tweet above, my sign is attached to my magnetic white board. The 32 x 32 panels used to come with magnetic feet. I think this is the separate product you can buy if you want to attach your sign to a magnetic surface: https://www.adafruit.com/product/4631
I'd welcome suggestions for better bmp creation / editing software. I just modified a 352 width x 32 height box in Photoshop. Make sure mode is set to Index Color using the menu: Image > Mode > Indexed Color
Image must also be no greater than 8-bits, so also select the menu: Image > Mode > 8 Bits/Channel
When editing, treat every 32 bits (or 64 bits for the 64 bit panel) as if it's a frame in the grid that's animated by the python code. the swift.bmp has 10 images, so you'll note while loop resets to grid_index = 0 after the 10th image is displayed.
NOTE: Since Adabox 016 added a 64 x 32, you can use the code above, just change the matrix_width = 32 to 64. Also make sure you use images that support 64 bit width. Only one up here so far is yoda_sip.bmp which is baby yoda sipping soup.
