The interwebs are the kind of place that if you don’t watch yourself, you can find yourself wandering into all sorts of odd locations.  This thing is called a RealTouch.  It’s a USB controlled masturbation aid (like guys need some kind of aid) that synchronizes with especially encoded video pornography streamed from the publisher’s website:

Correct me if I’m wrong, but shoving your junk into a caterpillar track doesn’t seem to be a good idea.  Am I the only one who thinks of radio-controlled toy tanks when I look at this?  Remember to only use it with the shell attached kids!  There’s a heater built-in too.   Again, I’m not sure that strapping an electrical heater to your Johnston is one of the cleverer things you could do today.  There’s also some kind of thing to disperse lubricant.  All this for a bargain-basement US$150!

Apparently, computer controlled masturbation is a well documented field more precisely called Teledildonics.  It appears that geeks, given the opportunity to combine computers and self-pleasuring, didn’t attempt to restrain themselves and went in full-tilt.  There’s even a wiki dedicated to Teledildonics, with a page on this very device; it’s all very technical (your salami experiences Parallel Axis Actuation using two motorized belts).

Which is why you shouldn’t click on weird ads.
