Welcome to the Easter egg Challenge

So I wanted to make this website fun, liking how coding is!

There exists a number of hidden features within this website, and you'll have to think like a developer to find them all!

• Find a great image done by my friend Neil Morley The Lazy FoxPush buttons on the site, whats the worst that could happen?
• Find a picture of our dog Doo
• What's one of the first things you do, when you visit a website that you like? You want to see how everything is built right?
• Mistakes happen, they suck but the error pages don't have to. A specially created page on this site will throw a custom error, but the page isn't listed in the navigation. What two files commonly found on websites can provide more information about pages of the website?
