I was just reading up on Create Digital Motion and they recently posted an interview with a highly known visual artist, Anton Marini. Marini has been doing visual art for some years now and has a very big part in the open source / visual community. He uses multiple programs to create stunning pixelated videos.
Truly inspiring. It is great to read up on other visual artists and their expressions on the whole idea/community of art through videos. He talks about different open source free programs that are out there that many people use to create wonders. The only thing is it is very time consuming, like all great things. But at the same time, very rewarding when the final product is done. I definitely recommend checking out his other videos as well.
