Four Keys Tap, Rock & Roll

My first attempt & a better Kee4.com Keyboard RefCard with relative keycap legends  


Tke kee4.com Refcard before reworking - They have not yet mass produced this kb.

108 Heptominoes



Proposed by Solomon Golomb in Scientific American
Originally done on pen and non-graph paper in high school
Grouped by maximum number of pixels in a straight line
Enumerated by permuting remaining pixels alongside these spines
Turns & Flips of pieces don't count - these are all unique shapes.

And the last two (in red) were only discovered after checking off my 106 from a Wikipedian list.
