dd(8) with progress

I needed to write an iso image to a USB key, and the typical way is
with just dd(8), but I wanted a progress bar. A quick google later,
and I get:

pv -tpreb isoname | sudo dd of=/dev/sdd bs=1024

Which will write the iso image to the USB stick sdd, and give me a
progress bar, tell me how fast it is writing, and give me an eta when
finished. Perfect.
