Kanji come in many forms, just as the Latin script has serif, sans-serif, slab serif, and various handwritten forms. Stroke order and direction are accentuated the most when Kanji is written with a brush on paper, which many computer fonts try to mimic. But the strokes can be made much less prominent when the letters are carved into stone or wood. You can even use a brush to flow all the strokes from several letters together into a long, virtually illegible squiggle [1]. Modern instruments like fountain pens produce different results, and pencils are still more different. There are different customs and standards of penmanship for each writing instrument.
The duct-tape typeface looks rather similar to seal script [2], an ancient style that is still commonly mimicked when, obviously, people carve seals (inkan).
It's not similar to seal script at all. A lot of seal scripts are unintelligible to me, even when I know what Kanji it represent. This is mostly legiable.
I'm talking about the style of the strokes, not the structure of specific letters. The example shown on Wikipedia is thousands of years old, of course the letters looked different then.
