It seems Sikuli was inspired by iMacros:

Sikuli has been around for a year or so, but that a side iMacros looks like it is clunky and difficult to use. Where as Sikuli is Python and awesome.

The IDE installs and runs in whatever system language you have activated in Windows - with no option to change it other than java command line parameters.

That's quite a shitty user experience for many people right from the start.
