S*a*D|Meph put together a whole bunch of trick jump demos from the
Kingpin single player maps.
To view them just extract the rar file to a temp folder somewhere and
then copy the demos into kingpin/main/demos. Then just add +map
demoname.dm2 to your kingpin desktop shortcut.
You can grab the trick jumps rar file from here -
