Guessing you really have to be a fan of the show to appreciate this Star Trek Transporter Room Bath Mat and Shower Curtain.
If you are, it's probably a must-have. Based on the Transporter Room from the original 1960s series (and officially licensed), you get the 'scene' as a shower curtain, with the mat being the pad you stand on to transport. Of course, you'll not be going anywhere – but you will come out miraculously clean (if you turn the water on). You'll have to do your own sound effects too. Shame.
$49.99 gets you the two pieces.
