Lïtbørd (more than some assembly required)

09/06/2020

As you may have noticed, a global pandemics got many of us working from home. While one can argue that you can do accounting from home, it’s a lot more complicated to teach from home. Pretty much everyone is trying to figure that one out. For my part, I decided that zoom and the virtual whiteboard is not very interesting. Like many, I decided to use a lightboard.

Sustainable iPod Rack
