My home office looks very much like this.
My older son, Benjamin, worked for a Japanese animation company for a while. He draws these images freehand. Notice the longitude and latitude lines are correctly placed also.
From my office, I have ‘traveled’ to many countries.
I remember once being in 13 different time zones simultaneously! No kidding.
A couple of days ago, I connected with a writer who worked for me from Kuala Lumpur but now lives in Singapore.
