## Description

RadioacTV does *NOT* detect a radioactivity. It detects a difference from previous frame and blurs it.

RadioacTV has 4 mode, normal, strobe1, strobe2 and trigger. In trigger mode, effect appears only when the trigger property is `TRUE`.

strobe1 and strobe2 mode drops some frames. strobe1 mode uses the difference between current frame and previous frame dropped, while strobe2 mode uses the difference from previous frame displayed. The effect of strobe2 is stronger than strobe1.

### Example launch line
