I'm hoping if I lay the groundwork and create this thread that @dvsDave or @gafftaper will come by with a great video explaining it better, but LightShark was probably on my top 3 list of things that I'll tell a customer to buy before next LDI. They where showing 2 products inside the WorkPro booth. A fader wing and what they call a "core DMX engine". Both could transmit up to 8 universes of DMX. and they connect to touch devices (Ipad, iPhone, that Android tablet you have no use for anymore, etc...) to use as screens for a digital control surface. They had fixture profiles, an elementary effects engine, OSC and other standard show control connectivity, and a lot of other goodies. My memory is that the price they told me was $1k for the wing and $600 for the core, but a quick peruse of the internet makes it look like $1.5k and $650 is closer to reality. Either way I think this makes it one of the most economic sounding options for a school or similar environment. For my niche in the business, the ability to buy the LS-Core and stash it away inside a piece scheduled to play certain cue stacks at predetermined times it a really compelling option. There is also the ability to connect to these devices over wifi to trigger a cue stack from a phone or similar device. Needless to say, I was impressed. There was some chatter about this system in the LDI Day 1 thread so hopefully there are some people here with hands on experience they'd like to share about these units.
