I'm investigating encryption algorithms - can someone give me a quick rundown of the differences between Rijndael and AES?

AES is a United States federal standard, FIPS 197, which is a subset of Rijndael:

AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits, whereas Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits and a maximum of 256 bits.

From Advanced Encryption Standard on Wikipedia.
