"Bronto-belly futures are up?! Buy! BUY!!"

If dinosaurs ruled the earth, how would it be different?

My Halloween costume is a study in the corporate dinosaur. He's still ferocious, although more so on the trading floor than on the forest floor.

It was also an excuse for me to learn some new CAD tools. The tyrannosaurus head is made from 9 FedEx boxes, laser cut, folded, and taped together into a 3D, custom mask.

Step 1: Modeling the Dinosaur in CAD

Every project I've ever done that involved taking a project from CAD to physical object has required multiple CAD tools. This required 3 tools (6 is you count the tools I tried but which each gave unsatisfactory results for some operation), and I even cheated on the first step by begging a really nice tyrannosaurus rex model from a friend.

In Rhino, I removed the t-rex's teeth and tongue, and cut off the head.
what's sad is that T-Rex couldn't reach his ear hole with short arms even with that giant retro-cell phone of his.
Haha ,I love this work
Is there a reason to be anti-corporate? How about a Lobor Union dinosaur?? He he.
Awesome! I'll have to check out 123D for future projects. Any chance of a Mac native version in the future? I've been working on a folded Stargate helmet- sooo close to finishing.... gotta get back to work!
A preview of the software is available for Mac OS here:<br />http://www.123dapp.com/make
Awesome- thanks so much! I just spent some time checking out the site and it's pretty exciting stuff. I've already got a few ideas for some of my projects. :)<br> It would be cool to make a 3D grid model and fill it with foam and then shape it to make a positive model for complex paper mache shells.<br> <br> I showed your T Rex head to one of my co workers and we thought it would be fun to make a couple of different dino heads.<br> <br> I made some progress on my helmet too-<br> <a href="http://www.instructables.com/community/Its-alive-Alive/">http://www.instructables.com/community/Its-alive-Alive/</a>
Online versions is now live here!<br />http://apps.123dapp.com/make/
That is so awesome and super easy to use! I'm going to have a lot of fun with this with my kids. :)
We're working on 123D online, which will open it up to Mac users. To be released soon!
Sweet- thanks!
what did you use for the panels?(i may have missed it)
Card board boxes.
Great stuff, Although I would add some teeth to make it even more menacing
This is pretty cool, as for breaking it up into panels, you could also use a technique used by papercrafters.<br>That is, using Pepakura, to &quot;unfold&quot; your model into pieces (of more than one panel) and then cut/fold/glue it.<br>You would have trouble doing it with cardboard, but with some sort of thick card it would turn out looking much neater (without all the perforations).<br>You can also do paper and fibreglass resin too (like this instructable: http://www.instructables.com/id/Cardboard-Halo-3-Master-Chief-Helmet/ )
I wonder - did you deliberately leave the perforations visible as some sort of artistic comment or feature?<br><br><sub>(<em>Personally</em>, I would have used masking tape to glue the edges, then used more to cover the perforations before painting.)</sub>
Good idea. Masking the perforations just slipped my mind in the rush to complete this for Halloween.
Awesome. Any chance that panel-decomposing software will be a prize in an upcoming contest?
Some, and maybe all, aspects of it will be free in a future version of 123D.
buy! BUY! Love it!
wow that's awesome! You should make an instructable dedicated to how to use that panel software.
Amazing!<br />Where's the shot of you chomping on someone's head at work?
