I have been a big fan and supporter of free software for Nikon DSLRs, created based on Nikon's SDK (Software Development Kit). The latest addition is Nikontrol 3K that can be downloaded for free here. The idea is that the official Nikon's Camera Control Pro doesn't support some of the latest consumer level DSLRs, not to mention its price tag of $150. The software works by connecting a Nikon D3000, D40 or a D90 via the USB cable to a PC and can:
remote control the camera from a computer
preview the last photographs taken
save images from your camera, with the possibility of keeping or deleting them from your device
transfer images to a FTP server
support time-lapse shooting
The current Beta version is a bit buggy, but this could be because I was trying to connect a D300s which is not on the list of supported models (I was still able to trigger the D300s shutter from the PC). I talked to the developers and they are currently working on fixing and expanding the software with additional functionality.
Make sure you read the supported documentation on how to install and use the software.
