Dave,
Difficult to get info on LTR, but progress is being made, some of the showhomes are coming along nicely...
Ok, look away if you don't want to know the solution to the first 'magic' trick...
When you perform the calculation on any two digit number, you always get a multiple of nine. If you look at the resulting chart, the symbols are a repeating set of nine, so whatever multiple of nine you have, the same symbol comes up. Next time you try it the symbol set changes order to appear clever...
