State constitutional restrictions on non-capital sentences

This article from my local Columbus Dispatch discusses the Ohio Supreme Court’s decision to hear an appeal from a “man sentenced to 134 years in prison for three home-invasion robberies [arguing] that his sentence was cruel and unusual.”  Because so few non-capital sentences have been found unconstitutional under the Supreme Court’s Eighth Amendment jurisprudence, the defendant in this case should not get too excited about his chances.  However, the Ohio Supreme Court has a history of thoughtfully applying its own state constitutional standards differently than the federal constitutional standards.

I have long thought that state constitutional limits on punishment ought to be applied much differently (and perhaps much more expansively) than the Eighth Amendment.  I know that many state have, in death penalty cases, interpreted state constitutional provisions dynamically, but there are far fewer examples of this in non-capital cases.  Do readers have any favorite examples?
