gravity's rainbow (Score 3, Interesting)

Is "Cryptonomicon" in any way inspired by Thomas Pynchons "Gravity's Rainbow"? While reading "Cryptonomicon", I noticed that some aspects of the book resembled some parts of Thomas Pynchons book "Gravity's Rainbow", they share parts of the humour (Cryptonomicons Giant lizards during the drug/dilerium trips) or the WW2 timeline, and both are written in a postmodernistic style. After searching a bit on the net I saw that many other people noticed this. While "Cryptonomicon" being not so philosophical and linguistic complex structured as "Gravity's Rainbow" (and thus IMO not in the same class as "Gravity's Rainbow"), it still gives a feeling of allusion to "Gravity's Rainbow" to me.
