Pi Sudoku is originally created for Pi Day (March 14 = 3.14).
Math geeks all over the world celebrate their math-geekiness on this day with pie-eating contests, recitations of the digits of pi, and occasionally fundraisers where math faculty get hit in the face with pies.
Rules: Fill in the grid so that each row, column, and jigsaw region contains 1-9 exactly once and ? three times. Happy Puzzling!

Via JankoDesign I found yet another Color Rubik Cube For The Blind designed by Konstantin Datz.
The last Rubik Cube on Yanko Design called Touch and Feel Rubik’s Cube has textures as tease for the visually challenged; this current iteration uses only Braille (there is also Braille Sudoku).
Colors embossed include green, blue, red, yellow, white & pink. One of the more sensible concepts in a long time that hopefully will delight the sighted folks too. Happy Puzzling!
