He's been done before by many great artists. Some of my personal favorites : [link] [link]
But I thought I would go ahead and do one myself as well. I needed something for my groups V-Day contest ! Check it out:
He stands about 10" tall and is crocheted from 100% acrylic yarn. His antennae are pose-ab;e and can be moved and placed however you like.
He is up for sale at my Etsy shop. [link]
