We are trying to achieve a parallax "fly in" effect for different text boxes over a statically placed screenshot as the user scrolls down the page. Example of a similar effect on a different website: http://www.izoncam.com/. (Scroll down to the iPhone)
We know HubSpot COS can achieve this with custom coding. We have an excellent front-end developer in-house who's very familiar with jQuery and other web technologies needed for this. We already know about tutorials at w3schools, etc.
After searching the forum here, we read over this past post, but we are specifically looking for other HubSpot COS customers who have implemented parallax scrolling like this and to see what the simplest solution is before sinking lots of dev time into it.
