Sample category pictures make structure unclear

[davecparker]

In the Projects pages, categories and sub-categories are shown with a name and also an image. When the image is one of the actual projects, it can look to the user like just a gallery with only one item in it rather than a category. I suggest more abstract images for categories, or perhaps no images.

For example, on the starting Projects page, there appears at first glance to be just the little race car. If you make it past this, the next choice of hubs is more clear, but then inside Inventor it again looks like few choices, and you have to be persistent to make it all the way to seeing the Mini Loader sample for example.

A related issue is to consider whether the sub-category structure is more complex than necessary for now.

Thanks for the input!

It is currently structured like this because the tutorial pages are generated in the same way as the sets pages.

I feel like the whole site could use some work, but I went ahead and added the tutorial section recently anyway because we shouldn't hold back writing stuff in the mean time.

It should be easy enough to move things around later, so let's keep writing :)
