Hey Fivers!

Fall is coming! That means a lot more Fives and a whole slew of new projects to share with you. Thanks for sticking with me so far, I've got some new experiments to try and excited to see so many of you reaching out with cool things to share with me. Keep 'em coming!

Love,
Rohan

1. Holographic Mobile Displays
The folks over at LEIA 3D have recently been showing off their latest 3D holographic mobile display (understand the company name now?) with interactive touch technology. This is one of the world's smallest holographic displays, and it's designed to be implemented in mobile devices. How do you interact with the holograms? Well, the developer kit display shown above can sense "hover-touch" or touches above the display itself (giving you the impression that you can interact with the holograms). Should make for some really amazing interactive experiences once we can get the display resolution up a bit higher! [Source]
2. Human Tissue Simulations
This amazing SIGGRAPH paper showcases a new technique for the simulation of soft tissue deformations (basically, the way our skin and superficial tissues move and stretch). The tool the authors built will allow for much more realistic animations and renderings. Interestingly, these algorithms were developed by recording 10 individuals as they jumped and moved around in front of a high-resolution 3D capture system. The data was then used to build an model and later generalized to be applied to animated characters of varying BMIs (body-mass index). [Video]
3. Laminar Flow
Okay, this one isn't as much about new research or technology as much as it is just a great showcase of known physics. University of New Mexico scientists designed an apparatus to suspend color droplets in a fluid with known "laminar flow" properties (corn syrup, in this case). When the fluid is stirred, the color droplets smear around the container. However, when the fluid is stirred back to the original position, the color droplets regain their original shape (i.e. there's no mixing). It's totally unintuitive, so be sure to check out the video.

4. Obstruction-free Photography
Ever find yourself facing an obstructed view of a scene you're trying to photograph? Say a fence or window reflection? Well, some researchers at MIT have developed an interesting technique to use a sequence of images to separate an obstruction from the rest of the scene and remove it! The results are quite good despite the limitations -- do check out the video. Here's to hoping we can implement this automatically in the future: perhaps your camera/photos app could automatically take a sequence of photos and present you with an obstruction-less photo option later?

5. Water Gaming
This is an older project, but a good one nonetheless. In this project, researchers developed an interactive "touch" display that you interact with by running your hands through the display itself. How is that possible? Well, what if the display is made of an opaque liquid? A kinect overhead tracks your hands as they dip into the liquid and a projector augments your hands with special graphics as part of a video game. [Source]
