There are, of course, the super-cute bento lunches that are more art form than lunch item. See Exhibit A:
There are all kinds of really cute accessories to make eating lunch more fun. If you have kids, I bet they'd get excited about this. If you're a big kid yourself, you'll probably like it too.
This website has a lot of good tips about how to make speedy bento lunches (say, under 15 minutes of prep time), so it's a reasonable feat to attempt.

I recently visited my favorite Japanese store in LA, Marukai, and found some fun little egg molds.
You take a (still hot) hard-boiled egg, peel it, and plop it in the mold. Then you squish it closed, and pop it in the fridge or into a bowl of ice water to cool. When it's cold, you have an egg shaped like a star or a bear or whatever mold shape you have. I haven't tried mine out yet, but I'm excited to! I'll report back on how it goes! If you want your own set, you can usually find them on Amazon or a Japanese supply website.
