How stuff works is a fairly comprehensive site explaining how myriad things work using illustrations and clear text. It also has a powerful search engine to help you find answers to those little things that keep you up at night...like the sleeping patterns of whales & dolphins...and how campaign finances work. Hope you find in helpful, it placed 51st on Britian's Telegraph "The 101 most useful websites" where you are bound to find other great resources.
There are several online photo editors available, however, FotoFlexer appears to be the most full-featured to date. Try it before logging in, I think you will find it is easy-to-use with many of the expected features you might expect; but I was pleasantly surprised by the "Geek" tab for advanced options in addition to allow saving multiple layers. For the novice users it has an "Add a face" option which I'm sure we can use to brighten someone's day, happy photo editing.
This Historic Tale Construction Kit has been around for a couple of years. I often use it to support one of my school projects for Page & Cover Design. Click Start and you can drag & drop images and use the text tool to create words (only one font available), unfortunately to save the images you need to use the print screen function with Photoshop for editing. I don't think this site supports multiple frames, email to a friend, or the gallery function any longer, still it is a clever way to create tapestry-like images if you have the patience to use print screen & Photoshop.
While I retain a playful spirit, my 30+ years in the graphics and media industry, from web pioneer in 1993 to UX director, teaching and creative lead, have honed my design skills across print, web, and interactive experiences.
