2nd fic search: Don/charlie and fractals?

[ptijade.livejournal.com]

So, me again,
this time, I'm looking for a vague fic, I think it's a slash Don/Charlie. Charlie is at home and decides to stay in the dark. He is alone and is lying on the floor, and looking at the ceiling he sees fractals. Don arrives and sees Charlie on the floor, he thinks he is injured but when Charlie reassures him, they end up together on the floor looking at the ceiling. Does it ring any bells?
