As the title states, the concept for this clock has been created by Lance Snider from AD, and many other marketplaces! 
In a try to get the file spread across all marketplaces, I agreed to recreate the clock in 3D, and upload it to 3D Ocean.
Here is the AD version of it… please drop by and share the love : http://activeden.net/item/generic-school-or-office-clock/7591
