I came up with an idea about a week ago for an SCP that has two entities.
SCP-XXXX-1: A standard camera that is altogether non-anomalous except for its developed pictures.
When a picture taken with the entity is developed, all Homo Sapiens in the photograph's arms will elongate, eyes will broaden, (other physical changes) etc. The subjects in the photograph, now referred to as SCP-XXXX-2, will change to reflect the physical form that they are shown as in the developed pictures of SCP-XXXX-1 over the course of about a week.
SCP-XXXX-2, after its full transformation is completed in the course of that week, will frantically try to grab SCP-XXXX-1 and either destroy it, grab SCP-XXXX-1 and take more pictures of Homo Sapiens, or kill any subject that is holding SCP-XXXX-1.
Idea is still a WIP.
Let me know if you think this is a good SCP idea or if you'd like to co-author with me. Looking for more experienced SCP writers to help me out with my first SCP. Thanks!
