Algodoo

How is it programmable? You forgot to provide instructions!

Well, it's easy ( sort of )
You just select one of the "led lights" and open script menu. You will see some arrays at _rec. You can program it if you want to

Oh, that's not the kind of "programmable" I was thinking of. What you described basically means that every Algodoo scene that uses Thyme scripting is programmable! When you said the display is programmable, I was thinking more like "configurable". In other words, if a user wanted to change the sequence of flashing lights, they would be able to switch certain buttons or change numeric values in variables, etc. So, they could "program" the lights by selecting external inputs, rather than editing the actual code. But you did not do it that way, and so it is not what I thought it was.

But it's still pretty cool!

I love the way it looks, it reminds me of the displays you'd see at the circus!

Thanks, Xray and Rastamoose!
