it was meant to be crazy, lol. Thanks for your comment. How long? idk - there were many artists involved, my own contribution took maybe a week or so on two separate occasions. But the project sat around for a number of years incomplete. There is another one in the works, started at around the same time and revived just now, after I sort of "kicked the can" with the video and social network postings: I am working on one panel now that would fill an empty spot, and after the coordinator of the project fills in a few blanks and joins them together, it would be finished also.
A exhibition is planned for next year August/September to showcase these and other cooperative projects of a similar nature.
