# Tombstone Matrix Portal ## Overview https://youtu.be/bdUgz8T7XeA In this project we’re making a tombstone with Adafruit’s Matrix Portal. We upgraded this foam tombstone with an RGB matrix so we can display animated graphics. The 3D skull is just a bitmap sprite sheet that is animated using CircuitPython. ![3d_printing_hero-wide-loop.gif](https://cdn-learn.adafruit.com/assets/assets/000/095/593/medium640thumb/3d_printing_hero-wide-loop.jpg?1602427415) The Matrix Portal is a plug-n-play dev board that makes these types of projects fairly easy. We designed and 3D printed these brackets so we can attach this to things like halloween props, picture frames or just some foam core. With CircuitPython, you can animate sprites sheets and display them on the matrix! ![3d_printing_pumpkin-spin.gif](https://cdn-learn.adafruit.com/assets/assets/000/095/622/medium640thumb/3d_printing_pumpkin-spin.jpg?1602441302) ![](https://cdn-learn.adafruit.com/assets/assets/000/095/627/medium800/3d_printing_matrix-attached-wide.jpg?1602442439) The bitmaps autoplay but you can also use the built-in buttons on the side to cycle through them! ## Prerequisite Guides - [Adafruit Matrix Portal](https://learn.adafruit.com/adafruit-matrixportal-m4) - [Pixel Art on RGB Matrix](https://learn.adafruit.com/pixel-art-matrix-display/overview) - [Sprite Sheet Animation](https://learn.adafruit.com/pixel-art-matrix-display/sprite-sheet-animation) ![3d_printing_portal-buttons.jpg](https://cdn-learn.adafruit.com/assets/assets/000/095/631/medium640/3d_printing_portal-buttons.jpg?1602442980) ![](https://cdn-learn.adafruit.com/assets/assets/000/095/629/medium800thumb/3d_printing_ghost-loop.jpg?1602442719) ## Parts ### Adafruit Matrix Portal - CircuitPython Powered Internet Display [Adafruit Matrix Portal - CircuitPython Powered Internet Display](https://www.adafruit.com/product/4745) Folks love our [wide selection of RGB matrices](https://www.adafruit.com/category/327) and accessories, for making custom colorful LED displays... and our RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier.
