If you have no arms you can still give a hug thanks to the Haptihug Telecuddle Interface from Tachi Labs. This device allows you to strap in and feel all that there is to feel regarding a hug. Epic.
The Haptihug Telecuddle Interface is an alright idea. If you love playing Second Life and love giving hugs IRL, then I'm sure you would love this. It does look a little dorky, but first steps in technology usually do. Check out the video of this bad boy in action. It's too awesome for words. It can only be described in hugs.
