I was telling my young cousins in their teens that back in the day every office and classroom had a massive projector that looked like a retro interpretation of a goose. At the beginning of a lecture the professor would wheel this massive hunk of metal to the front of the room and shut off the room lights. The metal hunk was transparent on top and shot a powerful beam of light up vertically and the goosehead would reflect the light onto the wall. The professor on transparent sheets of plastic and colorful pencils would give their lecture with writing and illustrations on the wall. This was before PowerPoint was a thing.

I can't tell you how exciting technology is sometimes that I literally can feel excitement about something like this whiteboard system while also feeling nostalgia for the past. Love this tool thank you Niko.
