I am learning Haskell atm, but really want a small to medium sized project I can sink my teeth into. Previously I've done cloth simulations, emulators, ray tracers etc when learning new languages. These aren't great for Haskell because I can't be bothered dealing with the OpenGL bindings, and besides, I want something new.

Preferably something that exploits functional programmings best strengths.

How about parser?

Also take a look at Write Yourself a Scheme in 48 Hours

Nice, bookmarked that one. – Justin Shield Jul 12 '11 at 10:15
Not overly keen. Have done something similar for Python before. – Dominic Bou-Samra Jul 12 '11 at 10:36

How about a fast, concurrent webserver? or messaging queue?

A bittorrent client would be along the same lines. Either that or distributed number crunching. – Justin Shield Jul 12 '11 at 9:54
@Justin Shield: Hmmmm I like this idea. I will have to look at the protocol and see if it's feasible to to do. Would be awesome fun. – Dominic Bou-Samra Jul 12 '11 at 10:35
@Chaker Nakhli: This is a great idea too. – Dominic Bou-Samra Jul 12 '11 at 10:36
I recall someone a while back implemented bittorrent clients in both Haskell and Erlang and did a comparison of the experiences. It was really interesting and might provide some inspiration, but I don't have a link on hand at the moment. :[ – C. A. McCann Jul 12 '11 at 15:05
@camccann please post the link here if you happen to find it. Seems interesting! – Chaker Nakhli Jul 12 '11 at 15:12

It might be interesting for you to help with one of Haskell's GUI libraries.

From haskell.org:

There is a large number of GUI libraries for Haskell. Unfortunately there is no standard one and all are more or less incomplete. In general, low-level veneers are going well, but they are low level. High-level abstractions are pretty experimental. There is a need for a supported medium-level GUI library.

GUI's have a reputation for being state-dependent, but the first 8 libraries listed aim at providing functional, "Haskelly" interfaces.

Try out BNFC http://www.cse.chalmers.se/research/group/Language-technology/BNFC/ and build yourself a interpreter... or a compiler. It's really great
