# Sequence Braiding
Sequence Braiding
Sequence Braiding is a novel network visualization technique for temporal event sequences and attributes. It is a layered network layout algorithm for creating visualizations. Layer assignment is done using multiple sequence alignment by event type. Nodes within layers are ordered hierarchically first by attribute bins and then to minimize edge crossings. Edges are bundled and smoothly routed across layers. The algorithm is robust to arbitrary ordering, absence, and duplication of events.

# Shapeshifting timelines
Shapeshifting Timelines
Shapeshifting timelines is a study aimed at understanding what shape of timeline works best for different types of data.

Sparqling
SPARQLING is a system for visual SPARQL query building based on the GRAPHOL visual language for ontologies.
The characterizing feature of SPARQLING is the idea to preserve and take advantage of the native diagrammatic representation of G RAPHOL ontologies, allowing the user to navigate it, and to construct a graph-based representation of the query over it through a simple point-and-click mechanism. The system then automatically transforms the graphical query into the SPARQL syntax.

VR Audioscape
Project made during Google Summer of Code 2017 for The Processing Foundation.
VR Audioscape is a VR application made with Processing that lets the user travel through a procedural landscape generated according to music.
Play any music from any app on your phone, then run the app. It will automatically use as input any sound coming as output from the phone.

Persistence of Vision Display
We built a clock that displays a series of arcs representing the time by rotating very fast a single LED strip and giving the illusion that the clock is made by continuous arcs of light.
The LEDs are turned on and off with appropriate timing, so thanks to the principle of persistence of vision, the eye is under the impression that what it's seeing is not a strip of LEDs rotating, but a continuous beam.
This display was made for the 30th anniversary of Quasar Design University, Rome.

The clock represents the passing of time. Each arc of the clock represents a unit of time. In the course of a year, the clock slowly becomes empty, arc by arc, shutting down completely at the end of the year.
The POV display was made in collaboration with Bruno Laurencich
Map of Reddit
The Map of Reddit is an interactive graph intended for the discovery of new content of Reddit. It is the result of hierarchical clustering run using user contributions in different subreddit as a similarity measure.

I also had a public talk at Data Driven Innovation 2017 about the map of reddit and more related studies I did:
Clustering Reddit
Abstract:
In this talk, I explore how to use data obtained from Reddit to better understand how the community works by applying clustering algorithms and some simple text mining techniques to the comments and submissions.

You Turing-Complete Me
You Turing-Complete me is a talk I did at Codemotion 2016, Campus Party 2017 and Google DevFest Bari 2017 about Turing Completeness in videogames.
Abstract:
Turing Completeness is a set of characteristics that makes any language able to be used to build a Turing machine, therefore to be used to write any program or define another programming language. Such characteristics are so simple that they can be found in unexpected places like videogames. "You Turing Complete Me" is a talk that explores weird Turing Complete places, including Pokémon and Minecraft.

Poopfest
Poopfest is a small experimental game with watercolour graphics. 2-4 players fight each other as birds. 1st prize for graphics and 2nd prize for gameplay at Global Game Jam Rome 2015.

Everything, from the background to the character animations, was handpainted, then digitalized.
Poopfest won the 1st prize for the graphics and the 2nd prize for gameplay at Global Game Jam Rome 2017.
Le Cicale
Le Cicale was a movie documentary about the old people of Rome that included watercolour animated sections.
Unfortunately, the project was never finished, but I like to show off my watercolors (:
