Our description of Derivative works is a summary of how international copyright is defined and implimented. It’s not something we made up just for this challenge.
Copyright - Derivative Works
Greg Bear has granted CGSociety permission to base this challenge on his novel, EON. As EON is published work we need to be very clear regarding how copyright works in this situation.
When you have finished your work will be yours - you hold the Copyright for it as a derivative work, inspired by EON, a novel by Greg Bear. You will be free to show your finished work anywhere you want as long as it is in a non-commercial context and you include in the credit these words inspired by EON, a novel by Greg Bear. You cannot make any claim or imply in nay way that you created the work for Greg Bear and must not allow your work to appear in any form under EON or Greg Bear imprimatur.
As a derivate work you can not use your work in any commercial manner without gaining written permission from Greg Bear.
The arrangment is reciprocal. Greg Bear does not have any claim to your work other than being the inspiration for it. Should it be used by Greg Bear or the publishers of EON they are required to seek your permission to use your work.
In no way is the challenge designed to generate art work for Greg Bear or anyone other than yourself – the entrant. If your work does in some way atract commercial interest then that is great – you just need to be aware of the way derivative works are defined and work.
