Digital flip-books are my new favorite thing. Made from a series of PDFs, they can be passed around via email, or posted to a website, facebook page, etc. Best of all, you can zoom in on the images for a better look, an invaluable tool when you have artists like ours, where every line and brush stroke begs appreciation.
After our now infamous crane accident, we are always looking at alternative ways to share artwork with our clients, since 25 years of carefully constructed printed samples and portfolios are no longer in existence and have to be rebuilt from scratch.
