In Esperanto, 'fulm' is the root word for 'lightning'. Time-lapse video in Esperanto is 'fulmfilmeto', literally translating to 'lightning video.'
Just like how Esperanto serves as the universal language, Fulm presents itself as a universal solution for a time-lapse screen recorder, as you can run it on Windows, MacOS and Linux. Instead of recording hours-long footage only to be condensed into a few minutes, Fulm saves you the pain and time by simply taking screenshots every x seconds (you decide) which then combine into a time-lapse video.
Currently, due to performance issues, the minimum number of delay between screenshots is 1 second. This is an issue I'm fully aware of and keen on fixing. However, if you're planning to time-lapse a long session that you wish to be sped up considerably, Fulm will work well for you :)
