This is a fairly common menu structure for Drupal developers to deal with, and depending on how it functions, it could be super easy. Here's the scenario: you need to display the 1st level of links in a menu horizontally, and the 2nd level in that same menu right beneath it.
There are at least two different ways that this can be implemented. The first is a static approach, where you do NOT need to show children of each primary link when hovering.

Drupal is a wonderful content management system. Any Drupal web developer will tell you that there seems to be a module for anything you can think of. For the most part, this is what makes Drupal so great. The community support is second to none and it's never too hard to find a module that suites your needs.
With that said, it's important to understand when there may be something other than Drupal that you should be using for a particular functionality. Commenting is the best example of this.
HTML5 has become quite the buzz word lately, and it's important for people in both developer roles and project management roles to understand what it really is. The term has been around long enough that clients are aware of it, and may begin to ask "so how will you incorporate HTML5 into our website?" Not knowing how to answer this could be disastrous when attempting to gain the trust of a potential client.
Finally got the time to put out the next release. I'm pretty happy with this one - I tied up a lot of loose ends and common feature requests. The most important feature is the circular support I added in. A lot of people desired to have a true infinite ciruclar effect (so there are no edges or walls), and I was planning on that for v1.4. However I was messing around with some ideas and in the meantime added in support for resetting the carousel to the opposite side very quickly when an edge is hit. Check it out! Here is the changelog:
