It's children who keep us young. Even when they're not so young themselves ... or maybe especially because they're not so young themselves! My son, who is not that far off 40 years old, has moved on from keeping me up to date with the latest in music, to keeping me up to date with what I can do with Photoshop.
Here's one of the results. I took my "Forever Blowing Bubbles" oil painting and turned it into neon line art ... such fun! Both are now available on Etsy.
