A tracking light device, otherwise - a followspot is a very necessary class of equipment in our profession. But  this type of equipment is outdated. Yes, exactly! 2020 , and we still use huge things, that need to be twisted, tilted, moved levers. Tesla has an autopilot on board. And we have levers to open the intensity or adjust the zoom. In addition, these things are very expensive.

    But! I don't want to use a classic followspot. Even if it's a very expensive model. This is a huge heap of iron that still needs to be dragged to the right position (under the disapproving views of the people who do this), bring special power, establish intercom with the operator and not have any opportunity to quickly change very accurately selected values ​ ​ of intensity or beam parameters.

    As modern practice shows - the industry has found a solution. Why not turn a fixture that is already mounted on the truss into a followspot? Moreover, the power and optical system of modern fixtures allows you to do this. There are different solutions on the market - this is a full-fledged control console with levers and a monitor that you need to turn/move/tilt. There are computer solutions. Complex, differently licensed, with the need to purchase additional proprietary equipment.

    At this stage, I remembered my specialty and thought... Why not to make a universal, simple system for these tasks by myself? After all, all the necessary requirements for the software have long been developed by me in the process of work on different locations. Well, and... you see the result and, hopefully, use it in your daily work.
