Old skool TextField plasma (dithered)

I had a quick poke into FontStruct last nite, some useful features had been recently added to that awesome online block font editor. I found one of my previously designed fonts called RUdigit?, it's pretty (experi)mental (check the pixel size, otherwise you won't get the idea).

That reminded me of an old Flash AS1 experiment of mine, where I tried to use predefined character set to display various shades of grey. We used to do it a lot in the C64 demoscene days – nostalgia had kicked in and I quickly mocked up an AS3 version of that old triple sinus plasma code.

Click the face above to launch, hit SPACE to randomise the plasma periods. And now get ready for the trick: try selecting the pattern as you would do with normal text.

No Pixel Bender here, just pure TextField™. It's pretty slow I must say but I didn't spend a second to optimise it. Maybe drawing a single character onto a bitmapData or using copyPixels would work faster? I might look into that again, most likely when the C64 nostalgia takes me over again sometime.

If you are new to this technique, have a sniff into the source. TTF font included. Enjoy.
