So, the divorce between Instagram and Twitter has now become official. The Facebook acquisition yesterday [3] pulled the plug on the API which allowed Instagram users to paste their photos directly up onto their Twitter feed. And, as our very own Austin Carr noted [4], Twitter needed its very own sepia-and technicolor-shaded filters, like, ASAP, please. And now, photos from one of the Twitter boys seem to suggest that a Twinstagram-sorta service could be on its way--in time for the holidays, says AllThingsD [5].

The site's founder, Jack Dorsey, has been busy coating [6] all the pictures [7] on his Twitter feed [8] a fetching B&W, which may or may not mean that Twitter's full range of photo filters are more than on their way--and given Instagram's huge surge [9] over Thanksgiving, Twitter is probably eyeing up the potential holiday market of festive revelers tweeting a B&W picture of the nose-hair trimmers gifted by their granny rather as an epicurean might eye up the contents of his fridge [10] during the Christmas period.
