ooooh a marker as in ink marker lol.. i thought like a sign or w/e
LEGO!!!! mindstorms is real simple. the rcxc 1.5 is soooo easy to program. and if its not enuf for u theres plenty of free languages u can download. as for making a track, its real easy. the hardest would probably be attaching a marker to the bricks. but hey, at the worst, itll be a ducttape or hotglue job.
