Found this on Outblush.com and I <3 it!
From etsy user bekathwia, this handmade gift will make any tech-saavy lover smile. (Note to self: The maker can't guarantee delivery by Valentine's Day, but hell, it's such a neat gift, you should order it anyway. Price? $150 plus shipping.)
This 1.5 inch tall Sterling silver pendant is handmade from 1mm thick sheet and tubing, depicting the internet-savvy sentiment <3, an ascii heart! Appropriate for showing your geeky ladyfriend how much you care. The < and 3 dangle freely, dancing near each other with the wearer's motions.
Available with a 19 inch long 3mm leather cord or Sterling silver chain.
