You are wasting a lot of real estate on the home page. All the page buttons are scattered giving it a very unpolished look and feel.
The see details button needs to change. Instead of making the picture the button that takes you to the page, change the "See Details" to "Specify Device", "Design Device" and "Control Device". You will include a "Build Device" that has a page with step by step tutorials that the user has to follow to fabricate the device themselves.
Take out the on hover effect where the image size changes. Its not the 2000's anymore.
The walkthrough button is lost in the top bar, it needs to be with the help and about buttons.
Clean up the top bar with all the branding. You will include the Fluigi, CIDAR and BU branding in the About Page.
