Not linear writen forms?

I’m curious if anyone here created a conlang which had a non-linear written
form?
E.g.
"I want you to write a long book."
in Bes Dis’z this could be written:
- segráf ratél pil sitár han.
- [seG\ra_Hf rate_H pIl sIta_Hr han]
- /you-write be-long book I-want this/

but it would be more Pesian to make "I-want" into a modifier:
- sitàr segráf ratél pil.
- [sIta_Lr seG\ra_Hf rate_H pIl]
- /wantingly-by-me you-write be-long book/

which could be written as

segráf ratél pil
     sitàr

or

segráf
ratél pil
  sitar
