Owners of the popular
Rigol DS1054z oscilloscope (and other 1000z, 2000, 4000, and certain 800-series scopes) can use the following tool to "hack" their scope and enable all the untapped "hidden" features of more expensive models.
On the Rigol 1054z scope in particular, the hack unlocks RS232, I2C, SPI decoders; it doubles the memory for reviewing captures, it gives several new trigger options, and increases the bandwidth from 50MHz to 100MHz.
