[math-fun] unusual things

Hello math-funsters, there is an interesting site here, http://www.futilitycloset.com/?new=true a representation of 1/7 in decimal on an ellipse. the other pages are interesting as well, quite amusing, in the same vein , http://www.laboiteverte.fr/ that one is original, very original, I counted at least 100000 original images and pages. http://www.laboiteverte.fr/?s=math like this 'etch-a-sketch' on a sphere : http://www.laboiteverte.fr/le-doodle-dome-de-tyco-lardoise-magique-spherique... and with Pi digits here ??: http://www.laboiteverte.fr/le-doodle-dome-de-tyco-lardoise-magique-spherique... This is what I call original. one drawback : the whole site is in french, not the images. Have fun. Cheers. Simon Plouffe
