Hi - we found that our son fell in love with sand and water play when he reached that age, so we bought him a cheap square sand pit with a cover from ToysRus and he plays with it everyday. We also found that ride on toys are great, as are pop up tents & tunnels, they get to use their imagination more with these sorts of toys and start playing more independantly. Going to other Mums houses and playgroups are also great, that way you can use other peoples toys and houses as stimulation. I also borrow my friends toys etc before I buy them for my son, to make sure that he really does like them and will play with them for more than 1 hour... I also put on a wiggles DVD for him when I have to get something done like the dishes, phone calls or work on the computer, it seems to distract him for a good 10-20 minutes. I also try and get him involved in most things I do, like cleaning, gardening, getting the mail, he loves to help Mummy. I Hope some of this helps.
