Wed, 22 May 2013 19:13:16 GMT LentaLabs - showroom of unique products for sale on Ponoko http://www.ponoko.com/showroom/LentaLabs/4558 A Perpetual Calendar that covers 112 years from 1954 to 2065. Rotate top circle to match month with year, and it calculates the month's calendar for days of the week. Includes a mnemonic for month lengths and a reminder that time is very fleeting. Center hole is 1/4in. (6.35mm) and overall dimensions are 3.9in. (~100mm) in diameter I will have a bamboo option once I receive it from Ponoko. Mnemonic: Thirty days hath September, April, June, and November, All the rest have 31 Excepting February alone, Which hath but 28, in fine, Until leap year gives it 29. Poem: The days... come and go like muffled and veiled figures, sent from a distant friendly party; buy they say nothing, and if we do not use the gifts they bring they carry them as silently away.
