These days you just take a selfie standing in front of these things (with a short, detailed narrative and suitable emoticon or course) and post it on all forms of social media. Cos whats the point of owning / doing awesome **** unless the world knows, right?
The ATO etc could get by with a ******* Commodore 64 and spiral notepad.
