Finally...

since the expired date of the 'bridge project' is near...

we decide to cm out and meet at McD...

drawing out the bridge that we hv designed last few days with McD breakfast...i'm lovin' it...hehe ;-)

with the help of "SketchUp 7", we hv done all the job within two hours...

basically,our bridge is based on the idea from the bridge of Sydney Harbour...

after modifying,we get a better structure than that...

that is...

haha...jz for a joke ! ^^
