Goddamn Colour-Switching Dress (Dress illusion or Dress debate)
According to Stephen Macknik on CVNet on March 7-10:
1. Swiked originally tweeted the image on tumblr on February 25, 2015.
2. She did ask the 2AFC question, not the open ended question: http://swiked.tumblr.com/post/112073818575/guys-please-help-me-is-this-dress-white-and
3. She then retweeted herself on instagram on 2/27 (unless by some freak coincidence there is a different user on Instagram named swiked who just so happened to retweet the tumblr post).

The Illusions Parade (linked to ECVP and VSAC) is an exhibition/workshop event open to the public. It will bring together scientists and artists.
They will exchange knowledge and expertise in perceiving and performing experimental as well as artistic representations of illusions.
To exhibit in the gallery you will need to generate a new visual illusion (if you are a scientist) or an artwork representing perceptual illusions (if you are an artist).
Different techniques can be used, including: visual/audiovisual platforms, projections, installations, any form of painting and sculpture.
Deadline: April 1, 2015
