Ponoko Product Of The Week
Knowing where you are, and indeed when you are, is what this product is all about.
The Perpetual Calendar from LentaLabs is ingeniously simple in its operation and simply ingenious in its precision and construction.
To help you along, Russell has included a trusty mnemonic as well as a whimsical poem, which should keep your head on straight if the numbers start to overwhelm you.
The dates range from 1954 to 2065, which is fantastic both for time travellers and also teenagers who want to get invitations out early for their 70th birthday.
LentaLabs Perpetual Calendar is available in the Ponoko Showroom for $37.
