This iExpression replaces the source text of a text layer by a randomly generated line of text. Different kinds of text can be generated, e.g. binary numbers, numbers, or random strings using the letters of the alphabet. The text "mutates" over time, i.e. individual letters change randomly from time to time.
How many letters the text should be long.
Letter Lifetime (Secs)
How many seconds it takes until a letter changes on average
For 25, the same pattern repeats every 25 frames. The shorter the loop, the faster is the computation.
which symbols to use in the text (binary e.g. 100101010, numbers e.g. 9873548923, hex e.g. 19af21, HEX z.B. 19AF21, letters e.g. asfgdsdfg, LeTTers e.g. AlfDfaSA; LETTERS e.g. AGUAFZTCTAS)
Those characters are used, when the alphabet 'Custom' is choosen. If letters occur more than once in the alphabet, they are used more frequently, e.g. for 'aaabc' the letter 'a' occurs 3 times as often in the random text as 'b' or 'c'.
With this option the generated text also contains empty spaces.
Change this number arbitrarily to get another random text. For each number a different random text is generated.
Change for each Layer
With this option you get a different random text for each layer, if you apply the iExpression to several layers simultaneously
