I finally got around to watching this video...was this just a weird way to show case how u pull apart a machine to strip it n clean it...because if it was something different to a shop job n clean etc, I totaly missed it ?  I am confused.....also, nothing under the playfield was touched or even lifted...so what was all that about ??? 

Typical dealer shopout.  Strip the easy stuff, leave the hole through posts, pop bumpers etc......Hmm off topic.

Yep, as Oldskool1969 said, rendering and design work for a virtual pinball TZ.
