Over the last couple of days I've been playing through the co-op mode of Portal 2 with my brother and it inspired me to make an avatar. The original avatar was with my emote OC Syn, but as I liked the result so much I thought I would make one anyone can use.
This portal arrangement can only be made using the 4 Portals in co-op. One character (Atlas) controls blue and purple whilst the other (P-Body) can create orange and red. If you set them up in the correct positions you should be able to make an infinite loop like this. In practice it would be difficult to do due to the change in momentum, but its a nice set of theoretical portals xD
For the record, I haven't played either Portal or Portal 2 single player yet. Helping my bro complete co-op first since the PSN is down. And I play as Atlas.
If there's enough interest I may release a blank version if other people want to make a copy with their OC. For now though, you can edit the icon to use as your avatar, but please ask permission if you wish to upload your version to your gallery.**Feel free to use this avatar on your deviantART account without asking permission. However please do not claim it as your own work or upload it as an unchanged deviation. You can view my other free avatars on this page
