One of the recurring themes on the trade show floor was user and consumer privacy. I was excited to see one of my favorite privacy companies Ghostery with a booth and very friendly staff. According to one staffer, this year they were seeing a noticable shift in public awareness with more people understanding and interested in internet privacy products than ever.

Blink FX looks amazing, and the company had a big booth at the expo. They will be debuting their product today, with the help of LL Cool J. The individual wearable LED lighted devices can put audiences into the lighting design of any show, as they pulse en masse and in synchronicity to the beat (or tension) of music or stage productions. They're controlled by DMX512.

Old favorites had sprawling booths, and this included mobile battery makers Mophie - with their newest chargers on display and for sale. Companies like Mophie used the expo as an opportunity to socialize with their customers and the atmosphere was relaxed.

On display: the Mophie Juice Pack battery case for iPhone 4/4S ($79.95), which doubles the battery life of the phone, just like the Mophie for Samsung Galaxy S3 ($99.95) that I used throughout SXSW 2013.

There was no shortage of products focused toward the creative sector, which was refreshing after hearing so much general sentiment that 'white collars' held majority in attendee demographics (as aopposed to creatives, which many felt were in the minority more than usual) at Interactive.

Motus Digital Motion Capture Studio held court with hands-on demos and more.

The Electronic Frontier Foundation - the world's leading organization dedicated to defending civil liberties and digital rights - had a trade show booth as well as workshops, panels and sessions for EFF's SXSW 2013.

Simple and elegant docks for Apple products: I'm glad I discovered Henge Docks at the expo. Their upcoming product the Gravitas Dock ($69) is on my 'want list' and now available for pre-order. It's a weighty, sleek matte aluminum dock with sturdy changeable inserts that keep an iPad, iPhone, iPad Mini or iPod Touch upright for use and charged.

The Aurasma demonstrations had trade show attendees gathered and in awe. In fact, I immediately downloaded the free app and took a brochure to dinner after the expo to show my colleagues how it works.

HP's augmented reality platform (SDK, iOS and Android, free) uses a smartphone (or tablet's) camera to detect images and overlay rich media animations in 3D on top to turn an image into a visual experience. It's primarily pitched for print media, but here is an example of live-world overlay:

Another recurring theme at the expo was waterproof (and even freeze-proof) cases for smartphones and tablets. Above is Lifeproof's iPad case (starts $99.99).

This iPad lived underwater in a fish tank throughout the trade show.

Spotted: a Go Puck prototype for the company's next ultra-portable battery - in a carbon fiber case. I'm kicking myself for forgetting to go back and get the 2-for-1 expo discount for a Go Puck standard (it holds four times as much as a Mophie).

Many exhibitors had playful toys that often simply delighted passers-by. For example, to use this candy dispenser, all we needed to do was @ reply the company on Twitter and add the hashtag for which kind of candy we wanted it to give us. The company was a garder-variety domain registrar.

The Hatsune Miku phenomenon had a large presence at the expo. Hatsune Miku is a "vocaloid" - a singing, performing 3D virtual persona that has an enormous, devoted fan base. The female animation performs live concerts, and 'her' songs are crowdsourced (contributions from fans comprise much of the songs). As someone who covers a variety of tech trade shows (for over a decade), this exhibit completed my sense that the SXSW 2013 Trade Show was truly a world-class, unforgettable experience.
