Hello. I know these have been done before, especially easily with VCE. The different thing about this is, I decided to give it a shot with default events.
It uses completely default events and few named bricks.
Video Demonstration -

Pro/Con - Shutting down and then starting it back up will clear any work on it.
Cons - Because it uses named bricks, having multiple copies could be buggy. Fat and bulky just like old classic computers. Small monitor.
You may rate x/10 , be a little gentle on the rating due to knowing, this is evented entirely with default events.
