Litko released a new set of tokens with the NetRunner fans out there in mind (such as myself). Though, obviously, you could use them for a lot of different things.
From the announcement:
Now available! Upgrade your hacking games with LITKO’s Net Hacker Upgrade Set. This set features all the main tokens you’ll need for two players. Each token has been designed to enhance the game with easy to identify shapes and colors representing all the conditions during play.
