Utility to rotate text

Is there a utility that allows you to rotate text? For example, I want to rotate the following output from /usr/games/banner 90 degrees counterclockwise. I want to put up my email address in this fashion on my website.

Code:

 ##                 #
 ###             ####
 ###          #######
     ###  ########  #
        ######
            ###
                ### #
                   ##
        #           #
        #############
        #############
                   #
        #############
        #############
        #         #
        #          #
        #############
        ###########
           ##
        #######  ###
        ##    ## ####
        #     ##    #
        ##    #    ##
        ############
        ###########

        #                    #
        ######################
        ######################

        #           #
        #############   ###
        #############   ###

        #                    #
        ######################
        ######################
             ####
           ##### ##
        ######     ##
        ####        #
        #

Thanks.

Depending on Distro, you should he able to use the sysvbanner program, instead of banner.

I'm running NetBSD, and I know about /usr/bin/banner that is included in all Unix distributions, but I want to use the one in /usr/games because I think it produces better looking text. The /usr/bin/banner also produces text in all caps.
