“Guardians of Hidden Universes” is a playful story for experiencing on your phone in the street. You’re a Guardian of Hidden Universes, and when you check your Communication Terminal you find the Guild has made a terrible mistake they need you to repair. The experience lasts about 15-25 minutes, and takes you around whatever city you happen to be in. That’s right – you can play it in any city in the world! The app was launched at Popup Playground‘s 2013 Fresh Air Festival – a new pervasive gaming festival in Melbourne, Australia. This playful story is inspired by the idea of creating a locative-experience that is not site-specific. How can we have an experience than engages with the environment that also can work worldwide? The story is also playing with the idea of engaging with a character and a space and intuition within a short period of time. The short and playful experience is a Universe Creation 101 production. It was conceived, written, and designed by Christy Dena; with artwork, coding, and interface design by Elroy.

Cryptosystems based on the hardness of lattice problems have recently acquired much importance due to their average-case to worst-case equivalence, their conjectured resistance to quantum cryptanalysis, their ease of implementation and increasing practicality, and, lately, their promising potential as a platform for constructing advanced functionalities. In this work, we construct “Fuzzy” Identity Based Encryption from the hardness of the Learning With Errors (LWE) problem. We note that for our parameters, the underlying lattice problems (such as gapSVP or SIVP) are assumed to be hard to approximate within supexponential factors for adversaries running in subexponential time. We give CPA and CCA secure variants of our construction, for small and large universes of attributes. All our constructions are secure against selective-identity attacks in the standard model. Our construction is made possible by observing certain special properties that secret sharing schemes need to satisfy in order to be useful for Fuzzy IBE. We also discuss some obstacles towards realizing lattice-based attribute-based encryption (ABE).

"Nihilistic act embraces doomsday The Age – December 2012 By Rebecca Harkins-Cross For The Book of Revelations A WOMAN stumbles backwards through the audience, burdened by an overflowing backpack, muttering about the home she’s left behind. When she reaches the mountain onstage, she looks upon its cloud-swirled peak with awe. This stillness is ruptured by an involuntary outburst as she begins spitting out the scourges of the modern world – “nuclear explosion… war… car salesman”, she yells. This is the final show in La Mama’s explorations season, which allows performers to stage works still in development. Devised and performed by theatre maker and academic Alison Richards, it questions our eschatological paranoia that the end times are upon us. It is fitting then that it is premiered on the eve of the Mayan’s prophesised doomsday. Like many pilgrims before her, Ada (Richards) ascends the mountain in search of salvation, but her journey evokes sublime terror; she speaks in tongues, collapses into fitful sleeps. Richards combines operatic singing with an ethereal score by Faye Bendrups, her eruptions into song apparently brought on by the mountain’s ecstatic pull. Richards’ seraphic voice is haunting, the lyrics evoking visions of birth and death. But when Ada finally converses with the heavens, she does not receive the revelations she hopes for: the voice of the divine is nihilistic, urging her to accept the universe’s chaos. While the work is still fragmentary, unfolding like a dream, this is a powerful performance by Richards. Its striking imagery fails to cohere yet in narrative terms, but it is promising nonetheless."

Parody accounts are prevalent on Twitter, offering irreverent interpretations of public figures, fictional characters and more. These accounts post comments framed within the context of their fictional universes or stereotypes of their subjects, responding in-character to topical events. This article positions parody accounts as a ritualised social media practice, an extension of fan practices and irreverent Internet culture. By providing a typology of parody accounts and analysing the topicality of selected parody accounts’ tweets, the research examines how these accounts contribute to topical discussions. In-character framing of topical comments allows parody accounts to offer original interpretations of breaking news that receive more attention than their other tweets. The presence and longevity of parody accounts underline the importance of humour on social media, including within news and topical coverage.

A collaborative, performative and relational experience for two people, woven together by a custom digital phone App. Two walkers, who have never met, simultaneously use a phone App to record a personalised walk around their locality, crafting a series of special moments and surprises for each other. The App then allows participants to continue their two walks, but now directed by what the other person has just created for them. Finally, at the end of the experience they can then choose whether they would like to actually meet in person. Based loosely on the idea of a date, each participant is initially asked to give a little bit of personal information, and then actually speak volumes about themselves through how they choose to care for their 'date's future experience. After walking in parallel universes, but never far away from each other, both daters can ultimately choose to then meet in person -- if what they have experienced tells them that maybe "We Are The One".
