I have lots of *general* ideas.&nbsp;&nbsp;What I&#39;m hoping is that I can steal working code for one or two compelling examples, so that I can spend my time thinking about how to present it, rather than on dreaming up the example and writing the code.
</blockquote><div><br>Last night I thought writing a simple arithmetic calculator in Haskell would be pretty cool. Parsec makes it so easy to parse simple arithmetic expressions. Coming from a Ruby/C# background, that would really impress me - that kind of parsing isn&#39;t easy! 
<br><br>Not sure how hard it would be - but extending the calculator to different units or to symbolic expressions (i.e. simple variable assignments) would be impressive. <br><br>Sorry I don&#39;t have any code to provide :)
