Relationship Between Entropy and Internal Energy

can anyone tell me how to make such videos ?
I mean what tech do you use to make such educational videos ( writing on an imaginary board)

Here you go: ua-cam.com/video/YmvJVkyJbLc/v-deo.html
It's not an imaginary board -- it's a glass "lightboard". If you search UA-cam for "lightboard", you'll find lots of how-to videos
