Australia's Newest Dinosaur & 3D Printed Dino Bones

Modern technology meets prehistoric biology! Palaeontologists are using 3D scanning and printing to replicate dinosaur bones from INSIDE solid rock!

Dr. Phil Bell from UNE Armidale and Dr. Elizabeth Smith from the Australian Opal Centre in Lightning Ridge show us the world's most complete opalised dinosaur skeleton, along with some amazing 3D printed replicas of bones buried inside huge blocks of claystone.

Special thanks to Dr. Bell and Dr. Smith for their time, patience and knowledge!

How is a Video Rental Store still a thing in 2019?

Video rental stores used to be a thing. Now they're not. Some of the reasons are obvious, some you might not have considered.

I chat with Sam at Leading Edge Entertainment in Wodonga, Victoria, about operating a video rental store in 2019.

Lightning Ridge in 1988 - A Video Tour →

A (shaky) video tour of Lightning Ridge in 1988, courtesy of my late father, David Gawthorpe. I believe he filmed this with his new toy, a Sony Video-8 Camcorder, to show his family at Christmas '88.

This isn't a 'normal' IDU video, this is just an opportunity to archive a piece of Lightning Ridge history for posterity and the fun of it.

Elephants in the room:

  • I've edited the video a bit. There was a lot of crazy ground shooting and super shaky cam sections that were just hard to watch.

  • I've censored a few names that were mentioned, just to ensure privacy.

  • I've also removed a few uncouth bits of commentary.

  • Oh, yeah. Cancer sucks. Whack the donate button: https://www.cancer.org.au

Opal of the World - A World Tour of Opal, Part 2 →

We visit the Australian Opal Centre in Lightning Ridge and explore opal from around the world, including opal from Mexico, Brazil, Peru, Honduras, the United States of America, Canada, Ethiopia, Madagascar, Tanzania and Turkey.

Special thanks to Jenni Brammall at the Australian Opal Centre.

This is NOT an exhaustive look at all of the opal the world has to offer, there are many more locations that produce opal, and we'll visit opal from those countries in the future. Stay tuned, click the subscribe button, and we'll fill in the blanks in the future!

These examples were chosen from a selection of specimens; they don't necessarily represent the "best of the best" of each opal category. They're all beautiful, though!

This is by no means an exhaustive look at Australian opal.

In this series we’ll look at some incredible objects ranging from opalised fossils to opal mining heritage items to strange mystery objects that will make you wonder.”

Extras: A Space Shuttle, But Not

In July of 2017, we were lucky enough to spend some time in the United States, thanks to the generosity and hospitality of the Parker family. As a result, we got to visit awesome places like the Kennedy Space Center, the US Space and Rocket Center, and the National Air and Space Museum, all of which share the responsibility of being custodians to a full-sized (and in two out of three cases, flown) space shuttle orbiter. 

The US Space and Rocket Center in Huntsville, Alabama, is home to Pathfinder. You can watch Pathfinder's story here:

In July of 2017, I had the opportunity to visit the US Space & Rocket Center in Hunstville, Alabama -- home of Pathfinder, a replica space shuttle orbiter with a unique heritage, and an important part of the space shuttle program in its own right.

Here are some bonus photos from Huntsville, Cape Canaveral and Washington D.C.:

A Space Shuttle, But Not: Pathfinder →

There were only six space shuttle orbiters. There was also Pathfinder.

In this video, I explore the history of Pathfinder and the early testing stages of the orbiter program.

Update, as posted on the IDU Facebook page:

So, in my video about Pathfinder, the Space Shuttle mock up (kind of) at the US Space & Rocket Center in Huntsville AL, I said that Pathfinder was the “only full-size Shuttle on display in full stack configuration”. This is not true, as I totally forgot about the replica of Discovery at Space World Japan, which is unfortunately planned to close at the end of this year. I hope the shuttle finds a new and awesome home.

What's it like to Live in a Train? →

Graeme Anderson is a retired potter from Lightning Ridge, who creates amazing and unique opal clay pots. He also lives in a grouping of old Sydney train carriages, which he collected when they were retired from the network in 1992.

In this video we chat with Graeme about his unique home, and the challenges he had to overcome to make it a comfortable place to live.

Lightning Ridge is home to at least 20 former Sydney Network carriages, most of which have been converted into homes or workspaces.
