I thought some of you might like this. I've been using my mountain bike for commuting now that it's winter, but I don't have any good clipless shoes for around town. So I went to a scrap metal yard and found a small chunk of aluminum angle iron, cut it down with a hack saw and file, and drilled some holes for toe clips and cleats, and voila, Pedal covers that fit my egg beater pedals! They work fantastically well, and they're easy to remove, etc.
I've attached a few pictures...let me know what you think!
