Emotions play tricks on our memories, making our recollections of events much happier or heart-wrenching than they actually were. Smartphone app Expereal seeks to cut through those cognitive traps by allowing you to rate your day on a 10-point scale and organizing that data into easy-to-read charts.

The iOS app (Android and Web-based versions are planned) is the brainchild of Brooklyn-based digital strategist Jonathan Cohen, who was inspired by psychologist Daniel Kahneham’s 2010 TED talk “The riddle of experience vs. memory.” Kahneham argues that our memories are often distorted by cognitive biases. For example, one bad day can completely spoil someone’s memory of an otherwise pleasurable two-week vacation.

When designing Expereal, Cohen decided to stick to a 10-point scale to help users keep their ratings objective.

MessageMe — a messaging app that launched in March with a little Facebook controversy thrown in — has raised another $10 million, according to an SEC filing earlier today. The Series A round was led by Greylock Partners; and as part of it, John Lilly, the ex-CEO of Mozilla who is now a partner at Greylock, will be joining the board of LittleInc Labs, makers of MessageMe.

TechCrunch understands that others participating in this round are the same investors from LittleInc Labs’ $1.9 million seed round, including True Ventures, First Round Capital, Google Ventures, SVAngel, Resolut.vc, Andreessen Horowitz, and Social+Capital Partnership. The company’s angels also include Airbnb’s Brian Pokorny, Hiten Shah, Eric Wu and TinyCo CEO Suleman Ali.

Although the seed round was announced in March, just weeks after the launch of the app, it actually closed last year and went towards the company’s launch. This newest round will be used to help MessageMe keep up with growth in the future, as it faces up to an increasingly crowded field of competitors. They include biggies like WhatsApp and Facebook Messenger, both of which are popular across a number of regions; those that have built up strong followings in local markets, such as KakaoTalk in South Korea and Line in Japan; and newer contenders like the new Hangouts app from Google.

One of the most interesting product demos on display at Google I/O this year was a virtual sky diving simulation built using eight separate computers running Chrome, along with a Kinect-like motion sensor made by ASUS called the Xtion Pro. The Maps Dive experiment was created by Portland-based independent digital agency Instrument.

Developer Ben Purdy explained that they built the impressive tech demo to show what’s now possible with Chrome and how it can be used to create an amazingly rendered multi-display experience that looks like you’d expect it to be powered by current-gen gaming hardware instead of just a loose assortment of lightweight Linux-based computers running the kind of code that web developers are already comfortable with.

Maps Dive provided an experience that seemed at least as accurate and sensitive as your typical Kinect game. Purdy said that it’s really just an early example of things that could be built with the computers we already have, as well as mobile devices. Considering how far Chrome already reaches, imagining this type of experience running on even low-cost Chromebooks and Android tablets does open up a lot of possibilities.

NVIDIA brought its new Shield handheld gaming system to Google I/O this year and showed off a near-production device. The Shield made its debut at CES this year, surprising most since it’s a consumer handheld device from a company that generally makes internal components. But it has some neat tricks up its sleeve, including a Tegra 4 chipset, 2GB of RAM, a 5-inch 720p display and 16GB of internal storage.

The Shield units available at I/O this week were all running Android and showing off Android games with hardware controller support, and none were demoing the PC game streaming that NVIDIA said would be coming to Shield as a beta when it comes to retail in June.

My experience with the NVIDIA was limited to just a few games, including the Epic Citadel demo that always gets trotted out to demonstrate amazing graphics capabilities on mobile devices. There were also a couple of playable cart racers in action, and all of the above performed well and really showed that the hardware is capable of rendering high-quality video smoothly and without any apparent effort. For a device that’s essentially a smartphone without the actual phone powers, but with more physical buttons for $349, that’s an important achievement to be able to claim.
