This is a hockey helmet with the cage removed, spray painted white. It’s an extra-small, which is still a little big on a 21-month-old.

The lines were made with reflective tape used for pinstriping cars, so it lights up when the camera flash goes off.

The darker blue on the shirt and helmet is battery-operated glowing wire, purchased from glowire.com. They are not actually turned on in the picture.

The disc is a light-up mini flying disc by Flashflight.

The chocolate around the mouth is from a Kit-Kat bar, but I don’t think that’s really integral to the costume.

The costume idea was derived from the internet sensation Tron Guy after seeing him get a web redemption on Tosh.0. I actually contacted Tron Guy via e-mail and he gave me some ideas on how to make the costume. The armor he used was pre-bought and pre-laced with the electroluminescent wire… so this posed a problem for me. I decided that I would have to make the armor myself and find a creative way to secure it to the costume base. The arms are made from PVC pipe cut at 45 degree angles then sanded down and painted a powder white with plastic-adhering acrylic spray paint. The costume spandex itself is a “Green Man” costume from Always Sunny in Philadelphia, but in white. I had to remove the head from this and sew the neck around to the seam for a good fit, I also placed an eye hook for security so my back side wouldn’t randomly unzip. The shoulder pads and helmet are hockey gear powder coated white as well. Electroluminescent wire was run through the PVC, Shoulders, Helmet after measuring and drilling holes in specific areas. The wire was 4 feet per arm, 5 feet for the shoulders and 15 feet for the helmet. With 4 separate power sources I had to hide the battery packs. Each arm is hidden beneath the PVC, the shoulder pads is hidden under the right deltoid pad, and the helmet is hidden within the padding of the helmet inside. All blue paint was done with hand painting over 12 hours with acrylic paint.

Technology like cell phones, MP3 players and websites are so ingrained into our every day lives and we wouldn’t want it any other way. In fact tech is such a big part of our lives that now when trying to come up with costume ideas vampires and witches aren’t the first things we think of—it’s all about iPods and digg buttons. And apparently we aren’t alone. People are wearing all kinds of gadget costumes and even dressing up their children and pets like their favorite tech.
