What program did you use to do this?
I used the G.I.M.P (the GNU Image Manipulation Program). It's open source and pretty powerful for non-commercial software. It allows you to render a series of layers as an animated gif, which is what I did for this and my "Unfolding Cubes" piece. I'm glad you liked it.
Thanks for writing a review.
I think it would help if the animation held the full cube shape for a little bit longer, just enough to really be able to look at it. Just a thought.
Yeah, I agree. As it is, the animation loop slows down by a couple hundred milliseconds when it reaches the full cube, but it isn't long enough to get a good view. The problem I was having was getting the background animation to not look too out of sync with the cube or slow the overall animation too much. I made a compromise to balance things as best I could. If I do another version, I'm going to scratch the animated background and color shift altogether and just focus on the cube transformation. Thanks for the feedback.
