retro lineart sine-waves

Nikolaus Gradwohl2011-11-10T06:11:06+00:00

this little sketch was developed more on chance than on purpose, I was playing around with sin waves and visualizations of fft-spectra when I came up with this - It reminds me a bit on my first experiments with sine and cosine on my old Atari ST.

Just click on the sketch move the mouse

Retro-3D-Neon-LineGrid in processing

Nikolaus Gradwohl2010-09-02T06:07:21+00:00

I made some aimated neon 3d linegrid in processing, very retro-style.

It uses no openGL - only lines, just as i would have coded it in Basic on my Atari :-)

A Logo spiral

Nikolaus Gradwohl2010-06-15T19:58:00+00:00

For todays 30daysOfCreativity-Project I wanted to use a tool, that I haven't used so far. So I went back to the first programming language I have learned 20 years ago - Logo.

I used the kde KTurtle programm to write some logo code, which looks more like a modern IDE that the logo interpreter I remember :-)

$l = 1
repeat 64 {
  fw $l*2
  repeat 4 {
        fw $l
        tr 90
  bw $l*2
    $l = $l + 1
    tr 360/32

Visiting the Mailüfterl

Nikolaus Gradwohl2009-01-11T16:10:00+00:00

Today i was visiting the Technical Museum of Vienna and while standing in front of favourite exhibit - the Mailüfterl which is
the first european full transistorized computer - i thought it would be cool to see some code running on this machine.

back home i googled a bit and - tata - someone has written a emulator of the mailüfterl!
