Labyrinth of Worlds project is an Ultima Underworld II rewrite.
LoW is a rewrite of the first-person role-playing game Ultima Underworld II: Labyrinth of Worlds that came out in the early 1990s. One of the most celebrated game of its genre, this rewrite attempts to recapture the minutiae and spirit of the original.
At the moment, the tech demo allows you to walk (and jump) around all the Underworld II levels and worlds, has all NPCs and most monsters. You also get to see and manipulate all the dynamic objects of the game, and peek inside containers. The paperdoll has been implemented, too, and lets you access your inventory as well as wear/wield armor and weapons.
It is now possible to converse with the various NPCs. While not all the conversations work correctly (or at all) most do for the most part and it is now possible to actually understand the storyline. :) NPCs are also able to give items, now.
Another worthy project you might want to go take a look at is Underworld Adventures which seeks to recreate the first installement of that series and is doing a darn good job of it.
If you are an Ultima VII fan, then Exult is going to tickle you pink! The freshly released version 1.0 will allow you to play Black Gate and Serpent Isle with the addons on modern architectures, with a few gameplay improvements to boot!
Enhancements:
- Fixed executables
- new gameplay features, including wearable items
- improved user interface
- performance improvements
- more complete conversation support (including being given items),
- working keys and locks

Image::WorldMap is a Perl module to create graphical world maps of data.

SYNOPSIS

use Image::WorldMap;
my $map = Image::WorldMap->new("earth-small.png", "maian/8");
$map->add(4.91, 52.35, "Amsterdam.pm");
$map->add(-2.355399, 51.3828, "Bath.pm");
$map->add(-0.093999, 51.3627, "Croydon.pm");
$map->draw("test.png");

This module helps create graphical world maps of data, such as the Perl Monger World Map (http://www.astray.com/Bath.pm/). This module takes in a number of label locations (longitude/latitude) and outputs an image. It can attach text to the labels, and tries to make sure that labels do not overlap.

It is intended to be used to create images of information such as "where are all the Perl Monger groups?", "where in the world are all the CPAN mirrors?" and so on.
This module comes with a low-resolution image of the world. Additional larger images have not been bundled with the module due to their size, but are available at: http://www.astray.com/WorldMap/
