There is a hard (level 100) problem in projecteuler 566,   
   it is an intriguing problem about cutting a cake and flipping   
   parts of it. Then it magically returns to the original   
   situation where all the frosting is up. The cuts are irrational.   
   It is a bit theoretical, because million even billions cuts   
   are needed.   
   After years I came back to it, and I'm proud to announce that   
   it has been solved by a Forth program.   
      
   It has been posed june 2016 and I was the 266th solver.
