Bitcoins are an increasingly important online currency and GUIMiner is a simple miner designed to allow you to generate your own.
Note that GUIMiner isn't a standalone app. It requires the original Bitcoin software first as a server in order to create an online wallet with which you can connect GUIMiner.
GUIMiner is particularly suitable for those new to Bitcoin mining because it has a simplified interface to observe the mining status and speed plus a console with a history of activity.
