Shortly after the release of patch V6.15 Riot introduced a limited time (1st - 16th Aug.) special crafting that can be used to create summoner icons, special loading screen champion cards and skins related to the PROJECT theme.[1]
It follows the Hextech Crafting ideology but uses different kind of materials. Chests are called caches and don't need keys to be opened. Blueprints are like chests but instead of opening with a key they are fused with numerous cores to produce an item.
All the items can also be bought by 
RP from the shop.
Cache
Similar to a chest but unlocked thus no keys are used unlike in Hextech Crafting.
Starter Cache
By buying the event exclusive Summoner icons from the shop (
750 or 75) you gain the summoner icon and a champion specific PROJECT Cache. Each of these caches can be obtained only once.
EM Caster Cache

- EM Caster summoner icon
