4e Third Party Software

4e Turn Tracker -- GREAT! 4e turn tracker software.  Allows the DM to display a player only page, set up tracking for NPCs, monsters and PCs and their HP, effects, and turn related events.  The tracker actually allows you to move through the encounter turn by turn, and will pick up and drop off effects dependent on the status you have determined EoNT, SotNT, etc.  It is worth a read by anyone interested, since players and DMs can track for the party or the entire encounter!

Miniatures
Painted Fantasy Miniatures -- Miniature site with good selection.  They have a huge focus on Warhammer 40K and some of what they produce can be quite expensive.  They have D&D page with a small selection of miniatures.  It appears that the selection and gallery is still under construction.  Even if you want to buy your own basic miniatures and paint them yourself, this site will provide you with many ideas and color schemes!

20 Sided Woman -- 20 Sided Woman Blog.  Definitely a female perspective with female commentary.  Strays a bit off the ol' D&D path with other geeky discussion.  Interesting though.  She is a self-proclaimed nerd who loves all things geeky including LARPing, RP, video games like Mass Effect and many other related games, endeavors and commentary.  She also enjoys Terra Nova and vampire RPG.

Miscellaneous
Johnny Lee's Project Site -- Johnny Lee's site, of interest to us, includes a description of using the Nintendo Wii technology to create a cheap functional white board. Some players have used this to create a tabletop that senses the position of the player's chits, and updates a tabletop which is projected onto the table. Field of vision, fog of war, etc is calculated and updated automatically. A DM can use a PC to make other changes and move enemies and other objects throughout the tabletop, shown to scale and projected on the table.
