Will definitely be checking this article out in full. The techniques are of particular interest to me. It might sound exotic to outsiders but I do like the suspension of disbelief that kind of comes along with fantastic wealth.
I've used "hide vast sums of money" as the basis for a long, serious screenplay based on the Enron downfall of the early 2000s in the US. Currently in review for edits. If you'd like to read I can make it available by request.
