Accesibility in Kuala Lumpur

I learned an incredible thing the other day. I thought it was incredible. There are these patterns on the sidewalk. Sort of plastic lines with bumps on them running parallel to the sidewalk's edges. They are sort of yellow and previously, I had mistaken it for a norm that exists in Canada - urban modern art (i.e. art in the city that takes a form of the city, serves no purpose.. not necessarily is asthetically pleasing...and looks like it should server a purpose... first thing that comes to mind is that odd steal beam at leslie and sheppard (in toronto.. (ahh nested brackets) ) that really looks like it is (or was) there for a reason.. and not until somebody told me it was modern art did I realize it was indeed not serving a purpose) Back to these yellow plastic lines with bumps on them. Another reason I thought they were art is because they blend in with all the other muslim style medieval arabicesque stuff (like mosques) going on. But no!!! they are not useless art!!! They are there so that blind people can put their canes on them and guide themselves (so to not accidentally walk into traffic and such) Kuala Lumpur actually cares about accesibility! Go KL!
