No one can ever argue that when the Polycount Community comes together on something that the results are always a real treat for anyone to witness it.
The Dota2 Polycounters have spend the last several weeks grinding away on the Polycount Community Chest Event. A staggering 40 sets and items from 100 artists for Heroes across the spectrum have been crafted. Right now the community is focused on wrapping up the chest and submit it to Valve for potential inclusion into Dota 2 Store.
In the meantime, you can see what has been submitted and vote on the ones you like best here.
