While there is considerable debate whether or not QR Codes will “catch on”, they are beginning to show up in more and more places. Although a code can store as many as 4,096 characters of text in any format, QR codes are most commonly used to provide easy access to a web address. It makes sense, anything beyond a basic domain name is a pain for people to enter themselves, and while many services exist to alias URLs into shorter paths, the result is hardly user friendly.

Still, to many designers at least, QR codes are generic and ugly. Someone realized that QR codes implement error correction and that means that a certain amount of the data can be corrupted without losing effectiveness. For a long time, it was largely a trial and error process of deleting sections and seeing if it was still readable. Odds could be increased by padding the code out with additional data. But there is another way to better your odds. The secret was explained to me in this great blog post.

Here is the process I followed to create one for Artifacture. First, I created a QR code using one of the many websites devoted to offering that service. I used BeQRious.com.

After the doing the Gear invitation, and spending a little time in The Joule, we decided that it would be a good idea to create a Christmas tree that would fit in with the rest of the theme.  After some experimenting and brainstorming, we hit on the idea of counter rotating gears as the tree form.

To stay true to the feel of the place ( pictures below ), we elected to make the gears a combination of dark stained wood teeth around an acrylic core.  Since the tree would be moving, we decided against trying to make a set of meshed gears to drive the rotation – non-metal gears would mark, and would shed material over time even if perfectly meshed, so instead, we created a gear form with a silicone rubber contact surface.  It’s elegant looking, and simple to fabricate.  More importantly, it’s easier for the hotel staff to assemble and disassemble, and safer to guests and staff since there are no meshed teeth to create pinch hazards.

The photos shown are a 1:8 scale model.  The final tree would be approximately 7’2″ tall with the largest horizontal gear approximately 4′ across.  If we cannot reach an agreement for the Joule installation, we plan to make scale kits available next Christmas – and potentially full size ones as well.

The project began with a time crunch.  One week ( it actually turned out to be 8 days ) from first meeting to final delivery.  However, they were willing to let us go a little nuts, so we signed up.

For those who are not into puzzles and would rather just put your Frabjous together, here is a step-by-step video to follow.

We have long been fans of George Hart’s amazing geometric sculptures. One in particular, the Frabjous, was talked about in the Maker community, including an excellent explanation by Evil Mad Scientist Labs on why the pieces fit together the way they do.

Naturally, when we got our first laser cutter, we had to make a Frabjous. When George made his, he sanded the edges and glued the pieces together. While I have a lot of patience, that seemed like a lot of work! But at the time, we happened to be exploring the use of finger joints for assembling boxes and thought perhaps it could be applied here. Sure enough, it could!

After a lot of refinement, we approached George about licensing the design for production. He was in the process of putting together content for the Museum of Mathematics (MoMath) opening in NYC in 2012, and agreed that we could produce it for MoMath. We are ramping up production so soon you will see it at a museum gift shop near you. In the meantime, you can purchase it through our Etsy shop. MoMath receives a portion of each sale.

We are very excited to announce two new outlets for our Eiffel tower model.  In the US, the 6″ and 12″ versions can now be found in the gift shop at the Dallas Museum of Art (DMA). The DMA online store currently offers the 12″ version, with the 6″ soon to follow.

The 12″ tower has also just appeared in the online and print edition of the Grand Illusions holiday catalog.

Grand illusions is a specialty retailer that deals in elegant, ingenious and beautiful items, from time honored illusions to mind bending science toys. A number of of our favorite things on our toy shelf have come from them, and we are genuinely honored to be included in such an amazing collection.

Here, Grand Illusions founder Hendrik Ball shows off the tower:

This is a double first for us – our first time in a print catalog, and since they are a UK based firm – our first international distribution.
