I am Jaap Scherphuis, and this is my website.
I maintain several sub-sites here about things that interest me.
Here are a few other bits that don't have their own pages.
Downloadable version of my puzzle page, excluding the patent pdfs and large gallery images: puzzles.zip (36.4 MB)
The puzzle patents: patents.zip (86.0 MB)
The gallery: gallery.zip (676 MB)
