Here's a nicely color coordinated theme package based on the classic movie 'Creature From the Black Lagoon'. Everything is set in a mostly grayish tone with bright green in just the right places to highlight and make things stand out. The classic creature covers the desktop in an 800x600 bitmap wallpaper image that resizes well for higher and lower display sizes as well. There are just a few sound files but they are in all the right places. Desktop icons are made up of various other characters along with simple but very fitting cursors.
The zip archive contains a directory called 'Creature Classic' but the theme code references all theme parts from a directory called 'Creature'. (Make sure you rename that directory to 'Creature' when installing this theme package or it simply will not load properly.) 'Software\Classes\' also needs to be removed from the theme file code to prevent desktop icon problems for Windows 95 users.
This just goes to show that sometimes there really are big things in a little package. It could use a few tweaks as noted above but there's still quite a lot of quality in this small download. If you're good with tweaking those settings, go ahead and grab it. If not, wait for the update.
