What's a good beyond hello-world application to teach people iphone development
<p>I am going to attempt to teach some iphone application development at my job, over the course of a few weeks. </p>

<p>I am wondering, what is a good application to create over the course that would be interesting, yet not overly complicated.</p>

<p>Some qualities i'm looking for are:</p>

<ul>
<li>Touches on many features in UIKIT </li>
<li>Doesn't require too much
implementation edge case hell</li>
<li>Ideally interesting enough that
people are motivated by the fact that
they're making something they can
actually use.</li>
<li>Focus is on learning iphone development, programming knowledge is assumed.</li>
</ul>

<p>I know everything that could be an interesting app, already exist in the app store. I'm not worried about creating a never before seen idea. Just something interesting that meets the above points, and does not come bundled with the device</p>
