LED Light Pixel Art Experiment

Mint yourself free CryptoPunks in the LED Light pixel art series.

Here's the experiment - let's turn 24x24 pixelated CryptoPunks into LED Light art.

How?

1. Let's use a black background.
2. Let's change black pixels to a (lighter) shade of black (e.g. raisin black - rgb(36, 33, 36)).
3. Let's turn pixels into LEDs by scaling up the pixel (e.g. 8x).
4. Let's add spacing between the LEDs (e.g. 2 pixels).

Alien Punk #3100

Let's try alien punk #3100. Let's mint a fresh 24x24 copy.

require 'cryptopunks'

punks = Punks::Image::Composite.read( './punks.png' )
punk = punks[ 3100 ]
punk.save( './punk-3100.png' )

And let's try three LED Light variants:

1. LED - 8 pixels, Spacing - 2 pixels (the default)
2. LED - 16 pixels, Spacing - 3 pixels
3. LED - 16 pixels, Spacing - 8 pixels, Round Corner - Turned On

punk = punk.change_colors( { 0xff => 0x242124ff } )

punk_led = punk.led( 8, spacing: 2 )
punk_led.save( './punk-3100_led8x.png' )

punk_led = punk.led( 16, spacing: 3 )
punk_led.save( './punk-3100_led16x.png' )

punk_led = punk.led( 16, spacing: 8, round_corner: true )
punk_led.save( './punk-3100_led16xr.png' )

And Voila!

More Punks - Zombies, Blondes, Beanies & Friends

Let's try another batch of punks. Let's mint a fresh copy of zombie #3393, blondie #172 and beanie #2964.

ids = [3393, 172, 2964]
ids.each do |id|
  name = '%04d' % id
  punk = punks[id]
  punk.save( "./punk-#{name}.png" )
end

And let's try three LED Light variants:

1. LED - 8 pixels, Spacing - 2 pixels (the default)
2. LED - 16 pixels, Spacing - 3 pixels
3. LED - 16 pixels, Spacing - 8 pixels, Round Corner - Turned On

Let's add inside the loop:

ids.each do |id|
  # ...   see above

  punk = punk.change_colors( { 0xff => 0x242124ff } )

  punk_led = punk.led( 8, spacing: 2 )
  punk_led.save( "./punk-#{name}_led8x.png" )

  punk_led = punk.led( 16, spacing: 3 )
  punk_led.save( "./punk-#{name}_led16x.png" )

  punk_led = punk.led( 16, spacing: 8, round_corner: true )
  punk_led.save( "./punk-#{name}_led16xr.png" )
end

And Voila!

Future Directions - Comments Welcome

Really not too bad for a first rough quick & dirty LED light experiment.

Ideas for future improvements:

• Scale-up pixels not as rectangles but as circles?
• Use different shaded colors for scaled-up pixels?
• Use a background off by 1 for each scaled-up pixel for a neon "glowing" light effect?
• Your ideas here? Please, tell.
