+* Wavey Wind, the Modul-air Mitt
+
+  Using an ESP32 microcontroller with wifi and bluetooth capability, a gyroscope/accelerometer module and keyboards switches, I will be building an experimental low cost motion "glove" controller with a button for each finger.
+
+  The idea stems from an earlier abstract visualisation project which was intended to visualise music. After building the initial prototype and hooking it up with a touch user interface of sliders that modulate the visuals, I asked myself why should I make the program interpret music? We already do that when we listen and (can) react by dancing; using a motion sensor, the dancing can be "aplified" by turning bodily motions into shapes and colours projected on a surface.
+
+  Using the motion mitt, the operator of visuals doesn't have to get locked into a clumsy little touchscreen but can immerse in the experience of sound and video while co-creating it. A workshop will be held to build a number of gloves that can connect in an ad-hoc network, so that group of people could collaborate with them.
+
+  The glove(s) will send events via the open sound control protocol, opening the possibility to using using them for audio synthesis/modulation, or maybe even as a general interface.

+
+* Gibalna rokavička ("Wavey Wind, the Modul-air Mitt")
+  
+  Z ESP32 mikrokontrolerjem, ki omogoča wifi in bluetooth povezljivost, modulom z žiroskopom in pospeškomerjem ter tipkovničnimi stikali bom izdelal eksperimentalni nizkocenovni gibalni vmesnik z gumbom za vsak prst.
+
+  Ideja izhaja iz zgodnješega projekta abstraktne vizualizacije, ki naj bi odsevala glasbo. Po izgradnji zgodnjega prototipa z vmesnikom na drsnikov na dotik, ki modulirajo prikaz, sem se vprašal zakaj bi program interpretiral glasbo? To namreč počnemo že mi, na poslušanje (lahko) odreagiramo s plesom, gibalni senzor pa bi lahko telesne gibe "ojačal" v oblike in barve, projecirane na površino.
+
+  Z gibalno rokvičko se opravljalka_ec vizualij lahko izogne ujetosti v neroden zaslon na dotitk in potopi raje v izkušnjo zvoka in videa med soustvarjanjem le-te. Organizirana bo tudi delavnica za izgradnjo večih rokavičk, ki se lahko med sabo povežejo v ad-hoc mrežo, kar skupini ljudi omogoči sodelovanje. 
+
+  Rokavica oz. rokavice bodo pošiljale podatke preko OSC (open sound control) protokola, kar odpira tudi možnost rabe za zvočno sintezo/modulacijo ali celo kot splošni vmesnik.
