This is the website I made for my Mum, a talented and successful painter.
(To be fair, she's done a lot for me over the years too, but now we're even.)
The parallax effect and responsive design were achieved using hand-coded jQuery and CSS media queries. I wanted to hand-code it to show I could do it, but having done it, I'm now very happy to use frameworks to make life easier!
I could probably get a really good testimonial for this one, but I'm not sure how impressed you'd be by it...
