I find it very clever that a single shape would work for the entire alphabet. The X is not there but the again who needs the X?
xenophobe? => zenophobe
wax? => waks
exactly => ekzactly
exam => ekzam (ok this one looks and sound like Shazam!)
John, I thought that my second comment would have cleared that whole “there is no X” issue. I didn’t want to offend you or anyone. Your comment is definitely one of the best ones here, I mean it.
But are you sure that you are who you say you are? Or is there a new Guggenheim in The Netherlands?
