1 | # Dynaframe
2 | A Dynamic Photo and Video Picture Frame script written in Python. It was created to provide a simple way to do not only slideshows on a raspberry pi connected to a monitor, but to also do videos for effects such as cinemagraphs or plotagraphs. The initial version includes control via MQTT or HTTP, so that it can easily be controlled via home autoamtion or tablets/phones/computers remotely.

6 | This is my first Python project, so feedback is much appreciated!
