This may seem kind of weird, but how about having an open oven as the splash screen, with the biscuit inside and the buttons are, well, buttons.

Well this is moving along good, Carousel, I think you missed me on the list. I can do graphic design, minor coding, and any small things that need help.

While the oven idea sounds, as Topit put it, "Adorable." It seems like something that would be hard to do well.
Maybe as a promo ad, but not as a splash screen.

I'd say to go a more traditional shape with the screen, I don't really care for the odd shape of "3.0", and it seems different just for the sake of being different. But, how about something a bit more simple like having a bite taken out of one side? That would go along with the food theme, but may not be as distracting or difficult as some fancy geometric shape.

And I'm sorry about not having an updated version of my splash screen up, I've just been quite busy lately.
Other than the double outlines on the buttons, are there any more specific ideas that ya'll would like to see?
Also, here's the original GIMP .XCF image file, (I think that will work.) if somebody else wants to try something as well.

Once the design of the interface goes underway, I think that it should be primarily monochromatic. A brown interface would look tacky and if we are going for a cleaner look, it may not be the way to go. Here is an Interface concept I threw together, but I think it's a touch dark and A bit empty, but it's a start. Also, it's just a concept to get some ideas brewing.

If you open the image in a new tab, it is larger and looks a bit better.

The style of that looks great.

I "made it". I used a template off of some website where most of the icons and stuff came from, and really all that I did was arrange to fit our project. I don't know if we are allowed to use any of that stuff for use in our program, or if I can redistribute it so here is the link. Also, the picture that I made from it is here. And yes, on a mac I would assume those would be in the status bar, and it's weird that I'm on a mac and I didn't even put in a status bar

Hmmm everything looks a bit big in your design - almost like I have accidently zoomed in on it or something!
I don't really like the interesting shape idea.
