    If you really want to see something, after you change to the palette of all hues,
    apply the frame set effect 'echos'. Add as many trails as you can handle. Say yes to the color shifting.
    Then play the animation on your screen.
    Looks like you've been quite busy, it's gonna take some time for me to dig through all of this. Great work!

    When I first tried the 'echos' effect I did it using option n (apply function effects by name) and it crashed, but when I selected the 'o' option and chose ild output and selected 6 (ild effect frame set), it worked fine.

    Well.....

    I have to admit, I have been updating stuff... exe ... math.txt...

    So DL current and please tell me.

    Sometimes I delete or rename the config file LaserBoy.wtf so that the app starts with a clean slate. With this new version, the background color defaults to white and the problem goes away when I restore the earlier wtf.

    That's weird.

    I did mess with that stuff a little. I made it so that you could set the background to white for exporting bitmaps. When you set the background to a light color to white the text that is usually white turns black.

    I think I fixed it.

    I did not make another release. Just DL current again.

    If you want just the Windows exe, DL

    Ran into another weird one... I was editing math.txt and I saved the edit as math2.txt so as not to overwrite the original. When I tried to open in LB, it did not give me a choice of which file to load, it just loaded math.txt automatically. I changed the name of math2.txt to joe.txt and then I was able to select properly.

    I am not able to reproduce this error. It works fine for me in both Linux and Windows.

    I get the same problem on both my laptop&desk machines. Are you sure that you had both math.txt & math2.txt in the directory
    when attempting to select an input file?

    Well, something is weird.

    I had a whole mess of txt files in my ./LaserBoy/txt folder. So I moved them all but math.txt and math2.txt and now it doesn't even give me an opportunity to type a file name. It just asks me how to load math.txt.

    I'll fix it.

    So have you made any of your own pretty math art with this new feature?

    Some other things I tweaked in this last update have to do with exporting bitmaps files. Now you can make them up to more than 37000 pixels square!

    Some time ago, I removed the limits of size (number of vertices) in a frame. If you have frames that are beyond 65536, LB can't save them as ILDA, so it offers to save them for you as formatted wave; which works perfectly.

    So now you can use the LaserBoy ASCII math forms to make vector images of hundreds of thousands, even millions of vertices and export them as HUGE bitmap files of insane detail.

    Why?

    To print!
