Sometimes it is super helpful to watch a video or animation to understand something technical before going into the formulas / algorithms, etc. So I wrote a skill that (completely locally) generates a video for you. You ask your agent for a video and it writes the animation code, prompts a small local model (LFM3-audio) to do the voice, and you get an MP4 explaining what you need to understand. Completely open source! Just check the github (linked) to install it :)
